Dear Family, your Operation Maths guide to Capacity

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of capacity. Also below, are a series of links to digital resources that will help both the children, and you, learn more about capacity. The digital resources are organised according to approximate class level.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • Where possible allow your children to have opportunities for “water play”; this can be during bath time, playing in the sink when the washing up is done, having tea-time with a play tea-set, playing outside with a basin of water and containers, etc. Sand play, if available, should also be encouraged as children explore with “pouring” sand from one container to another.
  • In school, the children are enabled to compare, estimate and measure capacity. You can reinforce this at home by asking the children to use their visual sense of capacity to compare and estimate which bottles, containers etc., hold more or hold less. Collect a selection of various types of bottles and containers and, if possible, remove any telling labels. Ask the children to line the containers up in order, starting with the one that they think holds the least. Fill this one with water, and then pour this water into the second container.
    • Does all the water fit? If no, then the first container holds more than the second container.
    • If yes, does the water from the first container fill the second container to the same level? Then they both hold the same amount.
    • Or is there space left at the top of the second container? Then it must hold more than the first container.
  • When estimating capacity, do the children realise that height and/or shape is not always indicative of capacity i.e. a taller but skinnier container may contain less than, or the same as, a shorter container.
  • When investigating capacity, try to conserve water; have a large basin handy, or do the water-pouring over a closed sink or bath so that the water can be reused. Why not even investigate the capacity of various containers as part of water play in the bath or sink?
  • Draw the children’s attention to capacity labels on bottles and containers, especially l for litres and ml for millilitres. Even children who may not yet know that there are 1,000ml in a litre, can examine labels and can use their number knowledge to identify the one which holds the most/least. If the item does not have a capacity label, does it have a label for a different unit of measurement and why is this? (e.g. perhaps g or kg for weight).
  • Is it good value? Keep a close eye on the capacity of various items when shopping (whether it be in the shops or online): while you’d expect that a 3l bottle of drink would be twice the price, or slightly less than twice the price, of a 1.5l bottle of the same drink, you would not expect it to be dearer – yet that can sometimes be the case! So involve the children in checking the capacity of items to make sure that you’re getting the best value for your money!
  • Find the items around your home that measure capacity (these are often called measuring instruments): kettles; liquid detergent caps and dispensers; medicine cups, spoons and syringes; buckets and basins; measuring jugs. Look carefully at the measuring scale, marked usually along the side, and get the children to try out these measuring instruments for themselves.
  • Involve your child in measuring capacity when cooking and baking. If using recipes, ask the children to calculate how much of each liquid ingredient would be required to make half, double, etc., of the amount/dish.
  • Enlist the help of older siblings if available. As they explain and support the younger members of the family, they will also be developing and consolidating their own knowledge and skills, especially communicating mathematically.
  • Draw the children’s attention to any other situation where capacity needs to be considered eg water conservation around the home, how much water we should drink daily, putting liquid detergent in the washing machine, the capacity of the household bins, the amount of rain forecast, recommended dosage for various medicines, buying enough paint for a particular room, purchasing fuel (eg petrol, diesel, home-heating oil), etc.

Maths by Month – April (updated 2020)

Category : Uncategorized

A new month is just around the corner, and as usual, this heralds the latest installment in this series of posts designed to explore the Operation Maths topics on a month-by-month basis.

This installment, however, is coinciding with a very turbulent and uncertain time in national and global history, as teachers and families around the country explore how best to continue to support children’s learning.

To contribute to this effort in some small way, we have launched a new series of posts entitled Dear Family. Each of these posts, will focus on a specific maths topic, and provide practical suggestions as to how families can support their child’s learning, as well as links to useful digital resources. We hope that, in some small way, they may prove to be beneficial, both now, and in the future. The first post in the Dear Family series focuses on the topic of weight, which all of the classes from third to sixth are likely to encounter in their Operation Maths books this month. Please feel free to share this post with members of your school community, whether Operation Maths users or not.

Dear Family, your Operation Maths guide to Weight

Category : Uncategorized

Dear Family, listed below are some practical suggestions as to how you might support your children’s understanding of the maths topic of weight. Also below, are a series of links to digital resources that will help both the children, and you, learn more about weight. The digital resources are organised according to approximate class level.

Junior Infants to Second Class
You can also find class specific tips at the back of your child’s Operation Maths At Home book, for infants to second class, and in the Operation Maths Dear Family letters for third to sixth class.

Practical Suggestions for all Children

  • In school, the children are enabled to compare, estimate and measure weight. You can reinforce this at home by asking the children to use their outstretched hands to compare and estimate the heavier/lighter of any two items, from anywhere around the house. Do they realise that size is not always indicative of weight? i.e. a bigger item (e.g. beach ball) may be lighter than a smaller item (e.g. a book).
  • The children can then check their estimate by using a handmade balance, assembled quickly from a clothes hanger and two identical bags.
  • Draw their attention to weight labels on food packaging, especially kg for kilograms and g for grams. Even children who may not yet know that there are 1,000g in a kg, can examine labels and can use their number knowledge to identify the heavier/lighter item. If the food item does not have a weight label, does it have a label for a different unit of measurement and why is this? (e.g. ml or l for capacity).
  • Is it good value? Keep a close eye on the weight of various food items when shopping (whether it be in the shops or online): while you’d expect that a 4kg bag of potatoes would be twice the price, or cheaper even, than a 2kg bag of the same potatoes, you would not expect it to be dearer – yet that can sometimes be the case! So involve the children in checking the weight of bags and packages to make sure that you’re getting the best value for your money!
  • Involve your child in weighing and measuring when cooking and baking. Show them your kitchen/digital scales (if you have any); demonstrate how it works and get the children to try the scales out for themselves. If using recipes, ask the children to calculate how much of each ingredient would be required to make half, double, etc., of the amount/dish.
  • Do you have any other weighing scales at home? Bathroom scales, luggage scales etc? Allow the children to explore how they work and use them to measure the weight of the bags used by the household: school bags, handbags, rucksacks etc.
  • Enlist the help of older siblings if available. As they explain and support the younger members of the family, they will also be developing and consolidating their own knowledge and skills, especially communicating mathematically.
  • Draw the children’s attention to any other situation where weight needs to be considered: weight requirements for children’s car seats, weight restrictions on baggage with airlines, weight restrictions when posting letters and parcels, etc.
