Maths

This week's maths learning is all about the composition of numbers within 10. 

 

Composition is the make up of the number e.g. how many smaller numbers can you find within 10, such as, 5 + 3 + 2 = 10

Lucky dip

You may wish to explore this by placing different coloured items into a bag or box that the children cannot see into. This could be different coloured bricks/ counters/ balls/ marbles/ socks/ cereal etc.

 

Ask your child to count out 10 items without looking then to lay them out on the table. Count how many of each colour they have picked then discuss. For example, they may have 10 socks altogether but within this 10, there are 3 green, 2 yellow, 4 blue and 1 black. 

 

You can advance to modelling how to write this as a number sentence:

3 + 2 + 4 + 1 = 10. Play around with different total amounts. 

 

Weigh it out

Have a go at making your own homemade scales! All you will need is a coat hanger, 2 x ties e.g. shoelaces/ string and 2 x pots/ buckets.

 

Place 10 of the same colour items in one side of the scales e.g. 10 black socks. Now experiment with different coloured socks on the other side e.g. 3 green, 7 yellow. Can your child experiment to find all the different combinations that make the scales balance? 

 

Penny shop

Create 5-6 different baskets full of treasures from around your home.

 

Give your child 10 pennies and explain that in your penny shop everything costs 1 pence so for 10 pennies they can choose 10 items. They will need to choose a few of the same items as you only have 6 different things... 

 

When they have filled their basket, count out their items and explore how many different items they chose, e.g. in a bag full of 10 items they might have 2 bracelets, 4 shoes, 1 badge and 3 buttons. This can again be written down as a number sentence so your child can clearly see that 10 is made up of smaller numbers.
