Number Bond or Number Fact:

Most textbooks define number bonds as the different pairs of numbers which make up the same number. E.g. All the number bonds for 10 are: 1+9, 2+8, 3+7, 4+6 and 5+5.

Number bond is typically represented using a picture consisting of 3 circles connected by 2 lines. See the examples below.

It is important to learn your number bonds up to 20.

At school we often talk about different ways to represent numbers.Explain the pictures below to your family so that you can all talk about numbers using the same language.

A SET

A collection of “things” (objects or numbers, etc). Each member is called an element of the set. There should be only one of each member (all members are unique).

An example: {1,2,3,4} is the set of counting numbers less than 5
