Explain the relationship between multiples of three and six

Maths

 In this unit pupils explain the relationship between multiples of 3 and of 6 and use this relationship and tests of divisibility to solve problems. In the future unit pupils will explain the relationship between multiples of 3 and multiples of 9 and use it to solve problems

In the prior unit pupils represented counting in 3s as the 3x table explaining the relationship between adjacent multiples of 3 and represented counting in 6s as the 6x table explaining the relationship between adjacent multiples of 6.  In this unit pupils explain the relationship between multiples of 3 and of 6 and use this relationship and tests of divisibility to solve problems.

Relationship between the 3 and 6 times tables and tests of divisibility

Look at the image. Match the size of the group to the number of groups.

Which numbers are both multiples of 3 and multiples of 6?

Multiples of 6 are {{ }} the multiples of 3

Look at the array. Match the questions to the correct answers.

If a factor is doubled, the product is halved

If a factor is doubled, the product also doubles

If a factor is halved, the product also halves

Which word or phrase describes multiples of numbers that are next to each other when skip counting?

Which number on this number line is not a multiple of 3?

Count along the number line up to the missing number

A multiple of 3 is missing from this list: 15, 18, 21, {{ }}, 27, 30   How can we use the adjacent multiples in this example?

Using your knowledge of groups, order the calculations starting with the smallest product.
