Apply calculation methods to questions and consider how best to support children

ContextContextSome children at BJR get a lot of support

at home, others get noneMethods and strategies taught at home

can be different from those taught at school

Resources: small world play, role play, counters, cubes, pairs of socks/gloves etc, models and images

Multiplication Y1Multiplication Y1

Doubling numbers e.g. 5 + 5 = 10.Say things like, “What is double 4?”The ‘X’ symbol is then introduced.5 x 2 = 10

Multipication Y1/2Multipication Y1/2

Arrays are used to show multiplication in a pictorial form. 4 x 3 = 12 or 3 x 4 = 12

This also illustrates repeated addition because 4 + 4 + 4 = 12 3 + 3 + 3 + 3 = 12

Update this page

Repeated addition along a number line: 6x4= 24

Children need to learn multiplication facts up to 10x 10 to make this process quicker.
