## Why Teach Number Bonds to 5

By the end of the reception year, children need to automatically recall number bonds up to 5 without the use of rhymes, counting or other aids. The reason they need to do this without any support is because it demonstrates that the children have developed number sense and thoroughly understand the composition of numbers.

Memorising the number bonds to 5 serves no purpose as children will not be able to apply their knowledge in more challenging situations, for example when solving addition and subtraction problems. If children know that 5 is made up of 4 and 1, they will also understand that 1 is left when 4 is taken away without the use of objects for support.

## Number Bonds to 5 Activities

Use the cute dogs to teach your children number bonds to 5 along with a range of other number skills.

The fenced area can be printed off either A4 or A3 size. A3 size would be useful to demonstrate the activity to the children in a small group, while the A4 size would allow the children to complete the activity independently. There are both small and large sized dogs to be used accordingly.

## Counting Activities

Place a number in the top of the field and ask children to put the correct number in there. Children may need help with number recognition initially if they don’t yet recognise their numbers. Some children will have a tendency to carry on counting beyond the number required until they have had lots of practice with this and have developed a strong sense of number. Children at this stage of development will not be ready to work on number bonds to 5 for a little while and will need lots of practical activities to develop number sense further.

## One to One Correspondence

The bones can be used to support the children with one to one correspondence. Are there enough bones for each dog? How many more do we need? Challenge the children further by asking if there are enough bones for two each.

## Number Bonds to 5

The split fenced area can be used to introduce children to the composition of number. You may want to start off with smaller numbers and gradually work towards number bonds to 5. Place a number in the top of the field e.g. 4 and ask children to put the correct amount in. Draw their attention to the amount of dogs in each side e.g. there may be 2 in one side and 2 in the other. Is there a different way that we could make 4. Children might need to be supported in putting 3 in one side and 1 in the other until they become familiar with the different arrangements.

Explore this further by putting 2 in one side and then asking the children how many need to go in the other side to make 4 or 5.

Once the children are confident challenge the children further by hiding half of the field so that the only information they have is the total number in the field and how many dogs on one side. Children then need to work out how many dogs there are in the hidden field using this information

## Numbers to 5 using hidden objects

The above resources help to develop the hidden concept further. Cut out the kennel and laminate. Attach to a box. Place a number from 1 to 5 on the front of the kennel. Place some of the dogs inside the kennel and some outside. Children, using their knowledge of the composition of number need to say how many dogs are inside the kennel based on how many they can see outside of the kennel. For example, if the number on the kennel is 5 and there are 2 outside the kennel, then there must be 3 inside the kennel.
