In this unit pupils will solve multiplication and division problems using knowledge of the scaling relationship between the 2x 4x 8x tables. In the future unit pupils will  represent counting in 3s as the 3x table explaining the relationship between adjacent multiples 3 and represent counting in sixes as the 6x table explaining the relationship between adjacent multiples of 6

In the prior unit pupils doubled and halved 2 digit numbers. They learned to use times table facts to find the quotient for 2x 5x 10x tables. In this unit pupils will solve multiplication and division problems using knowledge of the scaling relationships between the 2x 4x 8x tables.

In this unit pupils will solve multiplication and division problems using knowledge of the scaling relationships between the 2-, 4- and 8-times tables.

2, 4 and 8 times tables: using times tables to solve problems

Select the numbers which are multiples of 2 and 4 and 8

8 × 12 can help you to solve which other multiplication equation?

Match the expressions on the left which can help you to solve the expressions on the right.

Complete: If 9 × 8 = 72 then 90 × 8 = {{ }}

Andeep has collected 7 packets of 8 guinea cards. Izzy has collected 10 times as many as Andeep.
How many guinea cards does Izzy have?

What is the missing number in this sequence: 0, 10, 20, 30, 40, 50, 60, {{ }}, 80, 90, 100

Match the multiplication fact to the correct product.

Match the number to the correct product when the number has been multiplied by 10
