# Maths

## Multiplication and Division

Building on their knowledge of the 1, 2 and 10 times tables, the children will explore the 11 and 12 times tables through partitioning. They use Base 10 equipment to build representations of the times tables and use them to explore the inverse of multiplication and division statements.

## Vocabulary: Multiplication, division, inverse, share, group, partitioning, place value.

The children will use their knowledge to solve problems such as this:

Next the children will be introduced to the ‘Associative Law’ to multiply 3 numbers. This law focuses on the idea that it doesn’t matter
how we group the numbers when we multiply
e.g. 4
× 5 × 2 =(4 × 5) × 2 =20 × 2 =40
or
4 × 5 × 2 =4 × 5 × 2) =4 × 10 =40
They will link this idea to commutativity and see that we can change the order of the numbers to group them more efficiently, e.g. 4 × 2 × 5 =(4 × 2) × 5 =8 × 5 =40

We will also learn how to multiply 2 and 3 digit numbers and solve problems using our new skill.

## Vocabulary: Area, length, width, measure, multiply.

Children are introduced to area for the first time. They understand that area is the amount space is taken up by a 2D shape or surface.

Children investigate different shapes that an be made with sets of sticky notes. They will be encouraged to see that the same number of sticky notes can make different shapes but they cover the same amount of surface. We call this the area of a shape.
