Everyday activities to practise subtraction

As you would expect, subtraction is a key concept in the primary maths curriculum. Children start to learn about subtraction in their first year of primary school and it is something they continue to build upon all the way through to Year 6 (Primary 7). Here we have put together some easy activities that you can try at home to build your child’s skills and confidence at subtracting.

 

1. Counting backwards

Children are first taught to subtract by counting backwards. In this method, we start from the highest number and count backwards. Support your child by encouraging them to use their fingers to help count back. For example:
8 – 5 = ?
Start from finger 8. Count back 5 fingers. See where we land: on finger 3.
8 – 5 = 3

2. Everyday subtraction

Real life is full of opportunities for children to subtract, e.g. lending some toys to a friend and calculating how many toys will be left, or spending some money and working out how much money they should still have. Problems like this – about real things that children can see and touch – bring subtraction to life.

Teachers often ask children to solve life-like problems because it’s not numbers and signs on a page that children most need to deal with in life, but real events. The more we encourage our children to tackle such questions at home, the easier they’ll find them both at home and at school.

Try to find opportunities to talk about subtraction in everyday life. Ask questions like:

  • ‘You have 3 toy cars. How many will you have left if you let Charlie play with 1?’
  • ‘We had £15 of holiday spending money. We’ve spent £7.46. How much should we have left?’

3. Songs and rhymes

There are lots of songs that you can sing with your child to help them to count backwards. You could show them how to use their fingers, or toys, as props to help with the songs.

Find the ‘Five Little Ducks’ song and picture cards here. Print out and cut out the five duck pictures. Keep them as they are, or stick them to cardboard, and help your child to use them as props as you sing together.

With your child, make your own props to go with other subtraction songs such as ‘Five Little Monkeys Jumping on the Bed’, ‘There Were Ten in the Bed’, ‘Five Little Speckled Frogs’, or just enjoy singing these songs together.

4. Different words for subtraction

At home and at school, your child will come across lots of different words that mean subtraction:

  • Take away
  • How many left?
  • Minus
  • Less
  • Less than
  • What’s the difference?
  • How many more?

This can be confusing at first. For example, the word ‘more’ appears to be about adding something on, so phrases like ‘How many more … ?’ in questions such as ‘How many more does he have than you?’ can seem to call for an addition calculation. It takes lots of experience for children to remember that each time they hear these words they need to subtract. The more you use such words and phrases with your child, the easier they’ll find it when they come across them in school.

Ask subtraction questions using a variety of phrases. For example:

  • ‘You have 5 potatoes and Mina has 3 potatoes. How many more do you have?’
  • ‘This sweet costs 10p and that sweet costs 15p. What’s the difference in their prices?’

5. Play subtraction bingo

Playing subtraction bingo is a fun way to support your child to build their confidence at subtracting. Learning basic subtraction facts by heart can help children answer subtraction questions quickly and easily.
