Maths

Explain how groups of five and ten are related

Explain the relationship between multiples of five and ten

Use knowledge of the relationships between the 5 and 10 times tables to solve problems

Explain how a factor of zero or one affects the product

Represent multiplication equations in different ways

Explain what each factor represents in a multiplication story

Explain how a multiplication equation with 2 as a factor is related to doubling

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.

In this unit pupils will represent the 5-times table in different ways. They will explain the relationship between adjacent multiples of 5 and how 5- and 10-times tables are related.¬†

Representing counting in 5s as the 5 times table and link to the 10 times tables

Look at the image. It shows {{ }} groups of 1

10 times 1 can represent 10 groups of {{ }}

Which grouping of coins shows 1 group of 10?

Match the expression to the correct description.

Aisha has 2 of the same coin. Laura has one coin. She has the same amount of money as Aisha. If Aisha’s coins are both 10 pence, what is Laura’s coin? {{ }} p.

Select the correct number to complete the equation which represents the 10 pence and 5 pence coins. 2 × 10 = 4 ×  ___ p.

Look at the coins and complete with the same value.  {{ }} × 2 p = 2 × ___ p.

Which expression can be used to describe both sets of fingers?

Complete the multiplication equation needed to solve this problem.
If one packet of sweets costs 10 p, how many packets cost 60 p? {{ }} packets  × 10 p = 60 p.

If one packet of sweets costs 10 p, how much does 8 packets of sweets cost? {{ }} p.
