## How do you explain number bonds?

A number bond is a simple addition of two numbers that add up to give the sum. Using number bonds, one can instantly tell the answer without the need for the actual calculation. In the example given we can see that when we see a number bond, we instantly know the answer, without having to calculate.

## What is an example of a number bond?

Use a number bond to show a total and two parts for numbers 6–10. For example, if 9 is the total and 7 is one part, then 2 is the other part. Recall partners to ten (e.g., 1 and 9, 2 and 8, 3 and 7). Recall ten plus facts (e.g., 10 + 3 = 13; 10 + 7 = 17).

## How do you explain number bonds to 20?

Number bonds to 20 are the pairs of numbers that add together to make twenty. There are ten number bonds to 20, which are: 1 + 19. 2 + 18. The pairs of numbers that add to make 10 are:

- 1 and 9.
- 2 and 8.
- 3 and 7.
- 4 and 6.
- 5 and 5.

## What are the number bonds to 5?

Number Bonds of 5 – Primary Resources Number bonds are 2 different numbers that add up to a certain number. In this case number bonds of 5 would be 5+0, 4+1, 3+2 and then these equations reversed, 0+5, 1+4 and 2+3.

## Why are number bonds so important?

Number bonds help students see that numbers can be “broken” into pieces to make computation easier (decomposing/composing). With number bonds, students recognize the relationships between numbers through a written model that shows how the numbers are related.

## How do I start teaching number bonds?

Children start out by counting familiar real-world objects that they can interact with. They then use counters to represent the real-world objects. From here, they progress to grouping counters into two groups. By putting five counters into two groups, children learn the different ways that five can be made.

## When should children know number bonds to 10?

In Year 1 (age 5 – 6), your child will begin learning number bonds up to 10 – can they think of all the possible number pairs that make 10? They can then progress to learning number bonds to 20.
