Importance of Number Bonds

 

We believe that number bonds are a foundational to mathematical mastery. They also allow children to develop fluency and make calculations seem more meaningful.

There should be a distinction between 'learning number bond facts' (getting the facts into long term memory) and 'practise' (to improve the speed of recall).

 

Aims for Our Children

 

By the end of Year 1

 

Children should know by heart pairs of numbers that make 2,3,4 and 5

 

By the end of year 2

 

Children should know by heart pairs of numbers that make 6,7,8,9 & 10

 

By the end of Year 3

 

Children should know by heart pairs of numbers that make 11, 12, 13, 14, 15

 

By the end of Year 4

 

Children should know by heart pairs of numbers that make 16, 17, 18, 19, 20

 

By the end of Year 5

 

Children should be able to rapidly mentally calculate pairs that make 100 and pairs that make 1000

 

Methods for learning Number Bonds

The key ways in which we learn times tables at St Stephens are:

 

• Using concrete resources (such as cubes, unifix or counters) 

• Using pictoral methods

• Using doubling and halving

• Using near doubles (e.g. 7+8 by doubling 7 and adding 1)

• Bridging through 10 for number bonds between 10 and 20 e.g. 13-6 by subtracting the 3 from 13 to make 10, then subtracting another 3)

 

Children are given opportunity to practise their recall through activities such as through whole class rapid recall, card packs, head to head games and online interactive games.
