  • World Book Day is on Thursday 7th March, and while the primary resources accessible on the site are mainly literacy linked, there are numeracy ideas also, including “Not Another Maths Book” activity sheet. Other numeracy and literacy linked suggestions for this global celebration include:
    • Carry out a survey to find out the favourite books / authors of the children in your class. Or choose a page from a book. Work out the average number of words per sentence. Both of these are included among many other suggestions from Teaching Ideas for World Book Day.
  • With both Ireland’s ultimate and penultimate game in the 2019 Six Nations still to be played, there is still time to delve into some of the mathematical possibilities:
    • With older children, use the opportunity to explore the rugby union scoring system, and to identify what scores (up to 30, for example) are possible (how?) or impossible.
    • Calculate the number of games to be played; what if the competition had less or more teams, how many games would need to be played then?
    • Use the language of chance to discuss the possible outcomes for each nation in the competition and recognise that while it is impossible to predict the actual outcomes, we can use of knowledge of the teams performances to make informed predictions.
    • Calculate the dimensions of the pitch
    • Run a Fantasy Rugby League in your class
    • Make score predictions for each match and plot how these scores would be recorded on the Six Nations Table

Digging Deeper into … 2-D Shapes and 3-D Objects (infants to second class)

Category : Uncategorized

3-D shapes or 3-D objects?

In the PDST Shape and Space manual, it is suggested that “using the word ‘shape’ to describe both 2-D shapes and 3-D shapes can cause confusion for pupils”. For example, asking pupils to ‘describe the shape of this shape’ highlights one problem. Another problem is that pupils must be able to think of all cuboids as being ‘the same shape’, while mathematically speaking all cuboids are not the same shape.

The manual goes on to suggest that it would be more helpful to refer to 3-D things as ‘objects’. Using ‘objects’ also reinforces the notion that if it can be physically handled/picked up, it must be a 3-D object, as opposed to a 2-D shape which should always only have length and width, not depth/height.

So, throughout the Operation Maths books, this topic is titled 3-D objects to avoid confusion and to provide clarity for the pupils. However, wherever there is reference to “strand unit”, the term 3-D shapes is used, as this is the term used in the 1999 Primary Maths curriculum.

So what first? 2-D or 3-D?

2-D and 3-D objects are very inter-related, to the point that there is often much debate about which of the topic should be taught first; 2-D shapes, 3-D objects or teach them both concurrently.

Since 2-D shapes are lacking the third dimension of depth or height that their 3-D relations possess, this makes them quite abstract as only flat, drawn/printed shapes are truly 2-D. Whereas, 3-D objects can be picked up, manipulated, used for constructions etc., making them much more suited to the concrete learning experiences that are essential in the early years. They are the objects that we find in the real-world. Thus, since 2-D shapes are only flat representations of the faces of 3-D objects, it could be argued that it would be more logical, and more in line with the concrete-pictorial-abstract (CPA) approach, to teach about 3-D objects before 2-D shapes.

On the other-hand, it could be argued that 2-D shapes should be taught first as it is likely than young children would be more familiar with them. For example, the vocabulary of 2-D shapes features more regularly in common speak than the vocabulary of 3-D objects. Many children will likely have encountered many 2-D shapes from picture books and patterns around their homes, etc. And so, it remains inconclusive as to which order of progression is most beneficial!

In the Operation Maths books, the children meet the specific topic of 2-D shapes prior to that of 3-D objects each school year. However, it is envisaged that by the time the children in the junior classes are formally engaging with 2-D shapes, they have already encountered and informally explored both 2-D shapes and 3-D objects via the monthly themes (laid out in the long-term and short-term plans of each TRB) and in the suggested Aistear play activities (detailed also in the TRB) of which, the Aistear theme of construction is particularly relevant.

Infant classes

Whether considering 2-D shapes or 3-D objects, the suggested progression within each topic is very similar:

  • Undirected play
  • Sorting and ordering activities
  • Building and making (including making patterns)
  • Identifying

Undirected play may include sand and water play, use of formal construction toys, constructing using “junk” or found materials; any activities that allow the children to handle and manipulate shapes and objects.
In the Operation Maths TRBs for junior and senior infants there are ample suggestions for suitable activities, under the headings of various themes. “Undirected play” does not imply that the teacher is superfluous to the process; rather while the children are the instigators, the teacher can play a vital role, observing the way in which the children interact with the materials, and asking the children to explain what they did, how they did it and why they did it that way. This can be a great way to assess the prior knowledge and language that the children may already have.

Sorting and ordering activities include the Early Mathematical Activities (EMA) used early on in the infant classes; thus it is likely that shapes and/or objects have already been used as part of these activities, for example sorting and matching according to colour, size etc; ordering according to length/height etc.

At this point, the children should also be prompted to sort the shapes and objects according to their respective properties as relevant and appropriate:

  • Sort 2-D shapes according to the number of corners and the number and type of sides (straight, curved or both; sides that are different or the same).
  • Sort 3-D objects according to those that roll/do not roll, slide/do not slide, build/do not build, are hollow/solid; as a development, according to the number of corners and the number and type of faces and edges (please see end of post for more information on faces and edges).
  • The teacher can also isolate shapes/objects to create sets and then ask the children to identify the rule of the set: “What’s my rule?” (see image above). The children can also be encouraged to play the “What’s my rule?” game in groups.
  • Isolate a particular shape/object in the room and ask the children to locate others that are the same/similar and make a set of like objects/shapes.
  • The children may also be naming the shapes as part of these explorations; however this is not necessary as it is more important that they appreciate the similarities and difference between shapes, rather than identifying them.

Building and making with shapes/objects may have already been explored informally as part of the undirected play phase. The purpose now is to develop this into more formal teacher-directed tasks and activities:

  • Build the tallest building/castle that you can. What objects did you use/not use and why?
  • Dip a face of a 3-D object in paint and use it to print. Make a pattern using the prints. What do you notice?
  • Try printing with different faces of the same 3-D object. Are the resulting prints the same or different?
  • Push 3-D objects into sand/plasticine to make imprints. Or (if able) trace around the 3-D objects on paper to make designs.
  • Use cut-out shapes, gummed shapes, tangrams and/or pattern blocks to make pictures and patterns.
  • Use the shapes to cover surface of your book/mini-white board; which shapes did you use/not use and why?
  • Combine two shapes/objects to make a new shape/object.

As part of the building and making activities the children may begin to realise how certain shapes/objects can be combined to become other shapes/objects. Similarly, through the reverse of these activities, and other shape cutting activities, the children should begin to realise that shapes can also be separated (partitioned) to reveal new shapes. This can include deconstructing 3-D objects to reveal their net. These activities can be revisited once the children can also name the shapes/objects, so as to arrive at certain understandings and become more accurate with mathematical language eg that two squares can make a rectangle; that, when using tangrams, two of the same size triangles can be rearranged to make a square, a larger triangle etc.

Identifying the specific shapes/objects evolves from the previous activities as the children begin to realise that it is the specific properties and attributes of a shape/object that defines it, eg all shapes with three corners (and three sides) are triangles, irrespective of their size or colour and irrespective of the measure of sides and corners (later to be referred to as angles). Activities which will serve to reinforce this include “Guess the shape/object” using descriptions (see below), guessing unseen shapes/objects from touch (eg in a feely bag), locating a specific shape from a collection using touch alone.
Through the experiences of printing and imprinting with the 3-D objects, it is also hoped that the children realise that the flat faces of 3-D objects are in fact 2-D shapes.

First and Second classes

The children in these classes will continue to sort, describe, compare and name shapes as done in infants, but to now also include new shapes and objects i.e. semi-circle (1st), oval and cone (2nd). They will continue to construct and make shapes, extending this to creating and drawing the shapes themselves.

They will further explore the combining and partitioning of 2-D shapes, and this understanding will extend to include the fractions of halves (1st) and quarters (2nd). The properties of 2-D shapes will be further explored
in second class via the stand units of symmetry, angles and area (i.e. tessellating 2-D shapes)

Q: How many faces on a cylinder? Three or two?
Traditionally, in Ireland, and in Irish textbooks, a cylinder was recorded as having three faces. However, this is not mathematically correct, as strictly speaking a face is flat, and a 2D shape (figure), so therefore a cylinder has in fact only two faces, (both circles), and one curved surface. And while it may be argued that a cylinder has a third face i.e. the rectangular shape you see when you disassemble the net of the 3-D object, in this disassembled state it is no longer a cylinder, since it can no longer roll, a specific property of all cylinders.
Another way to think about the faces of 3-D objects is to consider the number and shape of the resulting outlines of tracing around, or printing, each surface of the 3-D object. It is only possible to trace around the opposite ends/bases of the cylinder, since only these are flat, thus it has only two faces, both of which are circular in shape. Similarly, it is only possible to trace around one surface on a cone, which therefore means it has only one face (a circle) and one curved surface.
And how many edges on a cylinder? Officially none, as an edge is where two flat faces meet and the faces on a cylinder are on opposite sides and do not touch/meet. However, that leaves the problem of how to describe the place where each face meets the curved surface.  So in Operation Maths, as occurs typically in other primary texts in other countries, there is a distinction made between straight edges (which are in fact true edges) and curved edges (which strictly speaking are not edges).

Digging Deeper into … Comparing and Ordering (infants to second class)

Category : Uncategorized

Of all the strand units in maths, this topic is one that is very close to the hearts of almost all young children:

  • “She’s got more than me! That’s not fair!”
  • “I want to be first!”
  • “I want to be the biggest!”

This strand unit evolves from the separate strand units of comparing and ordering that, along with the other two strand units of classifying and matching, make up the strand of early mathematical activities. The content objectives for this strand unit are quite similar across the four junior classes, with the main difference being the specific number limits for each class level:

Number > Comparing and Ordering >The child shall be enabled to:

  • compare equivalent and non-equivalent sets (to include the symbols <, >, = in second class)
  • order sets of objects by number (infants to first only)
  • use the language of ordinal number

 

Comparing

As mentioned above, even from when they are very young, most children are quite adept at comparing what he/she has with that of another.

As part of the strand early mathematical activities (i.e. pre-number) the children will already have had experience comparing sets by quantity (but without counting) i.e. identifying which of two sets has an obvious amount more (or less) than another. They will also have been identifying two sets/objects as being the same or different.

In Junior Infants, once children are comfortable establishing the cardinality of sets up to five, the next step is comparing and ordering sets of objects up to five. Since the amount of these sets may often only differ by just one or two, then it is not very obvious, from a visual point of view, which one has more or less. Comparing two similar sized sets requires that the child:

  • Can identify (and, later, write) the correct numeral for that set
  • Understands one-to-one correspondence, and using this can match the items in the two sets, so as to establish which one has more or less
  • Understands the conservation of number i.e. that a short line of five objects situated close together still has more than a longer line of four objects further apart.
  • Does not assume that the quantity of a set with objects bigger (or smaller) in size must be greater (or less) than the other set.

 

How many more?

Once a child is able to identify the greater set, the next step is to be able to state the difference between the sets i.e. how many more plates than cups? This can be a very difficult concept, with which children can struggle for many years.

As with the entire Operation Maths programme, a CPA approach is recommended when teaching this concept and, in particular, to use that which is most familiar to the children:

  • Use items that typically go together eg knives and forks, cups and saucers/plates, children and chairs/coats/school bags. Take a number of each and ask the children to suggest how we could ascertain the number of each. If not siggested by the children, the teacher should demonstrate how to set out the items in groups toegther eg the first knife with the first fork, the second knife with the second fork etc. If the quantities of each are not equal/the same, ask the children to explain how many more of the lesser quantity is required AND to explain how many extra items there are in the larger amount.
  • In a mixed classroom, use girls and boys. Call up a random group of children, ask the boys to line up at the top of the room, and the girls to line up in separate line beside them, so that, where possible, each child is adjacent to one other child in the other line (if you are lucky enough to have square tiles on your floor, ensure that there is a child standing in each square space). Ask the children to identify the children who have a match/partner on the other line and the number of children who do not have a match/partner on the other line. This activity could also be repeated using dolls and teddies, toy farm or zoo animals, attribute bears etc.
  • Use concrete manipulatives and pictures. Start with only two sets initially. Impress up on the children that the easiest way to see the comparison is to “line up” the objects, was done with the children previously. Use a grid of squares* to help with this. Once again, ask the children to identify where there is a “partner” fruit on the other line and the number of fruit that do not have a “partner” on the other line. These are the extras. How many more (extra) bananas than  apples? How many more (extra) bananas than  strawberries?  *The 5×5 grid on  the Operation Maths Sorting eManipulative is very useful here. The Operation Maths 100 Square eManipulative can also be used; select to show counters only and line up two (or more) rows or columns of different colours.
  • Ultimately, it is hoped that the children realise that it is not necessary to establish the exact amount of each set to be able to establish the difference between each set. In the example above, there are two more bananas than strawberries, and it is not necessary to identify the number of each fruit to establish this. This encourages the children to develop efficiency and flexibility in their approaches.
  • As the children move into first and second class, they should still be encouraged to “line up” the sets. If comparing the number of items in two static sets that cannot be lined up, eg an image in their books, the children can represent the number of items in each set using cubes and these cubes can then be lined up to make it easier to identify the difference between each set. This would link very well with their experiences of comparing quantities in pictograms and block graphs from the strand of Data.

It is important that teachers are aware that establishing the extra number in the larger/greater set and establishing how many less/fewer in the smaller/lesser set requires the children comparing the amounts in two different ways. In the example above, to identify how many more bananas there are than strawberries, requires identifying the number of bananas for which there are no corresponding strawberries. However, to identify how many fewer strawberries there are than bananas, requires identifying the number of empty spaces in the strawberries that there are, opposite the extra bananas. While the answer is the same both time, the route to the answer is different, and the latter approach requires the children to count empty spaces, which is more challenging due to its abstractness.

In second class, the children will begin to use the inequalities symbols (<, >). Many children will struggle with selecting the correct symbol to use, even if they can identify the larger or smaller quantity. Thus flashcards or reference cards such as the ones at this link can be very useful to connect both the language and the symbol. Interactive quizzes like this one from That Quiz or this one from ixl.ie can provide opportunities for extra practice. However, as emphasised previously, it may still be necessary to use a visual representation of both numbers being compared, for example using stacks of cubes, base ten blocks, straws or base ten money (10c and 1c coins). In this way, the children are now beginning to use their place value understanding also to compare quantities. As well as using the actual concrete materials, the Sorting eManipulative can be used to demonstrate how to do this using images of base ten materials; see Ready to go activities 2.3 and 2.4 as examples (screenshots below).

 

Hint: Developing the children’s ability to compare, will also be of benefit when they encounter the concept of subtraction as difference (as opposed to subtraction as deduction/take-away) and of further benefit when they are introduced to comparison bar models in third class up

 

Ordering

As part of a early mathematical activities, the children will already have experienced ordering objects by length, size etc. Now, they are extending this understanding to order by quantity.

In Junior Infants, once the children are able to count individual sets of up to five objects, this enables them to start ordering the sets of objects.

Counting and numeration are both very important when it comes to ordering:

  • The children are beginning to understand how higher numbers correlate with greater numbers of objects and vice versa.
  • When ordering sets we must also consider the number word sequence i.e. number five comes after the number four so five must be a greater amount than four.

 

Ordinal numbers

The nature of the English words for the ordinal numbers (first, second, third, fourth etc) and the nature of their abbreviated forms (1st, 2nd, 3rd, 4th etc) can pose significant difficulties for children as, at first glance, there appears to be little correspondence between the forms, and the abbreviations may not appear to follow any rule or pattern. Another difficulty lies in the apparent contradiction between ordinal numbers and cardinal numbers; it is typically better to have 10 rather than 1 of anything, but it is typically better to be 1st rather than 10th in any competitive activity.

  • Initially the focus should be on the spoken words only and the activities used should reflect this eg lining up children at the classroom door, asking the rest of the class to identify who is first, who is second, third, last etc.
  • When ready, flashcards of the ordinal words should be introduced and these can be incorporated into the familiar activities eg the flashcard with “first” can be given to a child who must give it to the child in that position in the line.
  • It is better to avoid using the abbreviations until first class and it is also better to start with the words, fourth, sixth seventh and tenth. Write the word fourth on the board and establish that the children can read and understand the word. Explain that for speed we want to find a quicker way to write/indicate this position and ask them to suggest what might be written to replace the underlined part of the word (ie 4th). Repeat this with the ordinal words sixth, seventh and tenth. Ask the children to suggest how fifth, eighth and ninth might be abbreviated and then finally ask for suggestions for the words first, second and third; ultimately, tell them the correct answers if they do not arrive at them themselves. In this way, the children are being prompted to discover the system of abbreviations that we use, as opposed to being just told.

Hint: For first and second classes, there is a list of online interactive games here which will help as extra practice. There are also lots of useful videos on YouTube etc; just search for “ordinal numbers”.

UPDATED! Operation Maths Assessment Records (infants to second class) on Excel

Category : Uncategorized

At Operation Maths we are constantly looking for ways to improve the usability of our programme, and to make it even more teacher-friendly. The most recent additions included long term plans for various combinations of multi-classes as well as excel versions of our Assessment Records. Following on from feedback from teachers, we have now expanded the original version of the latter, released in October last, to include all the assessments for the entire school year, as well as incorporating extra features designed to make them even more teacher-friendly.

 

 

 

 

While there are already word versions of these assessment records available to download from Edco Learning, as well as the hard copy photocopiables in the Teacher’s Resource Books (TRBs), these excel versions provide teachers with a more efficient and flexible way to both record and analyse the results from the Assessment Booklets:

  • Quickly get a total attainment score for each child (Assessment of Learning)
  • Use these attainment scores to compare the attainment of various individuals and/or groups of children and identify children in need of further support (Assessment for Learning).
  • Quickly get a score for each learning outcome, use these scores to identify the strengths and weaknesses of the class as a whole, while also being able to identify which learning outcome(s) require further consolidation (Assessment for Learning).

And this is all achievable in a very teacher-friendly way:

  • Each of the five assessments ( eg End of October, End of December etc ) has a dedicated page; click the tab at the bottom to move between them.
  • Teachers need only enter the children’s names once only on the first page; the inbuilt formulas then copy these names to the other pages in the document.
  • Under each child’s name, the teacher can enter a score for each question (or page in junior infants); see more below for a suggested scoring system.
  • The score for each individual question (or page) will be automatically totaled (horizontally across bottom) to give an attainment score for each child.
  • When all the scores have been entered for each child, these will also be totaled along the right-hand side vertically to give a total for each learning outcome.
  • After the five assessment tabs, there is a tab entitled “All”. Here all the scores from each assessment will be automatically replicated, once entered on the original assessment tab. This allows the teacher to easily view all the data in one screen. The scores for each child will also be totaled here to give you an overall score.
  • Other useful information provided includes the specific strand and strand unit (S.SU) to which the learning outcome relates. These are abbreviated and a full explanation of the abbreviation is given on the last tab.

HINT: If you already used the version of this document released last October, it is now recommended that you download and use these documents for the remaining assessments. They also include a page for the End of October Assessment, allowing teachers to copy and paste in the October Assessment scores, so as to have all the information in the one document.

Suggested Scoring System

While teachers can devise and use any system which they prefer, one option would be to try the following:

  • 4 = Question answered fully and correctly
  • 3 = Question answered fully but without full accuracy ie almost all correct
  • 2 = Has a majority of correct responses but a number of errors also
  • 1 = Some correct responses but a majority of errors
  • 0 = Not attempted or incorrect responses

Obviously, teachers will have to apply any scoring system in a flexible way; for example if there is a question that requires just one response and is therefore is either correct or incorrect, then only 0 or 4 will be awarded.

Once the appropriate score has been entered for each question then the teacher will have:

  • a total attainment score for each child; the higher the score the more learning outcomes achieved.
  • the means to sort and/or compare the attainment of various individuals and/or groups of children using these total attainment scores and identify those children with the lowest scores as needing further support.
  • the means to to identify the strengths and weaknesses of the class as a whole by sorting/comparing the total scores for the learning outcomes, while also being able to identify which learning outcome(s) would benefit from further teaching.

Downloading and using

The excel documents for each class level are available to download by clicking on the links below:

Operation Maths Jnr Infants Assessment Record BETA

Operation Maths Snr Infants Assessment Record BETA

Operation Maths 1 Assessment Record BETA

Operation Maths 2 Assessment Record BETA

You may notice that these are still BETA versions only. This is because we would welcome more feedback on the usability of these documents.

Feedback can be left on this Edco Primary Maths facebook post or messaged to Edco Primary Maths.

Some questions you might consider answering:

  • Did you find the excel document(s) useful?
  • Did you find the scoring system useful?
  • What suggestions would you make to improve them?

We welcome all feedback!
And it doesn’t have to be specific to these assessment records. Remember, that if you have any suggestions or any questions on Operation Maths, Number Facts or anything related to primary maths, please PM or contact Edco Primary Maths via Facebook and/or Twitter 


Digging Deeper into … Spatial Awareness

Category : Uncategorized

Spatial awareness…being able to describe the position of something/someone in relation to another using words and/or gestures, and being able to represent spaces and locations using models and/or drawings, may, at first glance, appear to have more in common with communication and geography, than with maths. However, the concepts of spatial awareness lay the foundations for all geometric thinking, be it at upper primary, secondary or an even higher level.

Essentially the children need to develop an understanding that:

  • The spatial relationships between objects and places can be described and represented.
  • These relationships may be viewed, described and represented differently depending on the perspective of the viewer (in particular, consider left and right).
  • Developing the ability to mentally visualise the representations will enhance a person’s ability to picture how a shape will look when rotated when turned, flipped etc.

A synopsis of the curriculum objectives for infants to second class, state that the children should be enabled to:

  • explore, discuss, develop and use the vocabulary of spatial relations (describing both position and direction/movement)
  • explore closed shapes and open shapes and make body shapes
  • give and follow simple directions (first and second class), including turning directions using half and quarter turns (second class only)
  • explore and solve practical problems (first and second class)

In the case of the practical problems, this could include completing a jigsaw or a tangram puzzle, using mazes, grids, board games and or exploring basic coding eg via coding programs and apps, such as Lightbot, and more hand-on devices such as BeeBots.

Moving through space

Since spatial awareness requires an understanding of using  space and moving through space, the majority of the activities should be active ones, where the children are moving around. This is where the suggested activities in the Operation Maths Teachers Resource Book (TRB) become extremely useful, such as the examples below.

Much of the language development in this strand unit can be reinforced via activities in PE (Orienteering) and Geography (mapping).

Digital Resources

While activities incorporating physical movement are preferable, the Operation Maths digital resources on edcolearning, provide a worthwhile alternative and add variety. The Ready to Go activities below, as the phrase says are “exactly what they say on the tin”; the teacher need only click on the relevant icon in the digital version of the pupil’s book to open the activity, and the accompanying suggested questions are quickly viewable along the side menu. A full description of the activity, including the questions, is also given in the TRB.
