An operation is commutative if the values it is operating on can be written in either order without changing the calculation.

A set of two factors, which, when multiplied together, give a particular product.

Represent multiplication equations in different ways

Maths

In this unit pupils will represent the 5x in different ways. They will explain the relationship between adjacent multiples of 5 and how 5x and 10x are related. In the future unit pupils will learn how a multiplication equation with 2 as a factor relates to doubling and how a division equation with 2 as a divisor relates to halving. They will explain the relationship between factors and products.

In the prior unit pupils represented the 2x 10x table in different ways using 2x 10x table to solve problems. They explained the relationship between adjacent multiples of 2/10 and that factor pairs can be written in any order. In this unit pupils will represent the 5x in different ways. They will explain the relationship between adjacent multiples of 5 and how 5x and 10x are related.

Look at the array below, how many groups of 2 are there? Select the expression which represents this.

The order of the factors can be changed and the product remains the same. This is known as __________.

Look at the equation: 5 × 6 = 30 Select the statements that are true for this equation.

Look at the arrays. Select the correct expressions that describe the groupings.

Look at the array to help you fill in the gap: 5 × 2 = {{ }} × 5

Aisha and Laura have some coins. Aisha has 20 p altogether. If Aisha has two 10 pence coins and Laura has the same 10 coins, what coins must Laura have? Laura will have 10 {{ }} pence coins. 

Look at the expressions 4 × 0 and 4 × 1   These have been shown with cupcakes. Which has the greater amount of cupcakes?

Look at the equation 2 × 6 = 12 Select the statements that are true.

Match the expression to the correct product.

Using what you know about 1 as a factor what is 15 × 1 = {{ }}
