Subtraction using objects to 10
Use biscuits and a biscuit tin to play a subtraction game with your child. Put 3 biscuits in the tin and ask your child to count how many biscuits there are. Ask them what would happen if Mummy or Daddy ate 1 biscuit? What would happen to the number of biscuits? Do we have more or less? How many would we have left? Ask your child to count the total biscuits left in the tin.
Show them the equals sign (=). Do they remember what it is and what it means? Show them the subtraction sign (-) and explain that when we use it in a sum our number gets smaller. Explain to them that we always start with a bigger number and take the smaller number away from it.
Model writing the subtraction number sentence: 3-1= 2
Using biscuits or other counting objects, encourage your child to have a go at working out the answer to these subtraction sums. Once they show a secure understanding, encourage them to write these sums as number sentences.
4-2= 5-3= 6-4= 7-5= 8-6= 9-1= 10-3=
Subtraction using objects to 20
Encourage your child to work out the answers to the following subtraction sums using hula hoops/crisps. This activity can be carried out using the same method as the ‘Biscuits in the biscuit tin’ activity from Monday.
10-2= 13-4= 12-6= 14-7= 16-8= 19-10= 18-4= 20-9=

Challenge: Can you use coins in your role play? What happens to the amount when we pay for an item? For example "I have 10p and buy a carton of juice for 5p. How much money do I have left?"
