## Dear Family, your Operation Maths guide to Fractions

Category : Uncategorized

Dear Family, given below is a brief guide to understanding the topic of fractions, as well as some practical suggestions as to how you might support your children’s understanding at home. Also below, are a series of links to digital resources that will help both the children, and you, learn more about fractions. The digital resources are organised according to approximate class level:

#### Understanding fractions

Fraction comes from a Latin word meaning “to break (something) in pieces”; it’s related to the word fracture, meaning to break into pieces, usually used to describe a broken bone. In maths, fractions are the result of dividing something (a shape, object or amount), into a number of equal pieces or parts.

Equal is very important; if we divide something into two parts, but they are not equal, then they are not halves. Therefore it is very important to emphasise to children from the very beginning that the parts made must be equal; in school we often talk about it being a fair share.

And while fractions might seem straight-forward enough, i.e. dividing something into equal parts, even the basic fractions can be interpreted in many ways:

3/4 (say “three quarters”) can be describing 3 parts of something that is is divided into 4 equal parts, eg 3/4 of the square is red (above) or 3/4 of the blocks are red (below).

3/4 can also be interpreted as three out of four i.e. that 3 out of 4 cubes are red or that 3 out of every group of 4 cubes are red (below).

3/4 can also be interpreted as three divided by four or 3 ÷ 4 which gives a value of 0.75, the decimal equivalent for 3/4 (below).

Initially much of children’s exploration of fractions in school, will focus on creating and identifying various fractions (starting with familiar fractions such halves, quarters, eighths, tenths etc).

They will also learn to recognise fraction forms that are the same value (i.e. equivalent fractions eg 1/2, 2/4, 4/8, 5/10 etc), and comparing and ordering fractions. In the senior classes, children will work with less familiar, more complex fractions as well as calculating with, adding, subtracting, multiplying and dividing fractions.

#### Practical Suggestions for Supporting Children

• Use fractions and the language of fractions at home, e.g. when dividing up food (cutting up pizzas, cake, bars of chocolate), when baking (e.g. half a teaspoon, a quarter of a cup, half a dozen eggs).
• Look for fractions when out shopping, e.g. half price. Ask your child to calculate the current price, or what the price was before the reduction.
• Be careful about using fractional language accurately, e.g. there’s no such thing as a big half or a small half! To make fractions, we must create equal parts. Encourage your child to be accurate and to recognise that if something is divided into two parts that are not equal, they are not halves.
• Fractions names can be confusing for children: it makes sense that each part of something divided into ten equal parts is a tenth… similarly for fifth, sixth, eighth, ninth etc. But each part of something divided into two equal parts is a half (plural is halves) and each part of something divided into four equal parts is a quarter. Furthermore, when speaking one eighth (1/8) it can be difficult to distinguish from eight (8). Try to say and explain fraction names clearly, and encourage your child to say them clearly also, so that they appreciate the difference between these similar-sounding words.
• If your child is experiencing difficulties with converting fractions, adding, subtracting or multiplying fractions, encourage him/her to use concrete materials (eg paper plates, paper straws and or pieces of paper) and/or draw pictorial representations, e.g. pie pieces or number lines, to help them visualise what is happening and develop his/her “fraction sense”.
