Multiplication and Division

Multiplication Understand multiplication as repeated addition. There are 5 pencils in one packet, how many pencils in 4 packets? or 4 lots of 5 or 4 x 5 1packet 2 packets 3packets 4packets

Your turn 3 x 6 =

When the children are comfortable with this we move onto repeated addition on a number line. 4 x 5 =

Your turn 6 x 4 =

From this we move onto using partitioning. 13 x 3 = 10 x 3 = 30 3 x 3 = = 39

Your turn 14 x 5 =

Move onto bigger numbers. 23 x 5 = 20 x 5 = 100 (2 x 5 = 10) 3 x 5 = = = 115

Your turn 32 x 3 =

Then we introduce the grid method. 3 x 23 = =69 x 20 3

Your Turn- 3 x 34 = x

Progress to vertical expanded recording, multiplying by the most significant digit first T U 2 3 x (7 x 20) 2 1 ( 7 x 3 ) 1 6 1

Your Turn- 35 x 4 T U

Division Begin by understanding division as sharing.

When we introduce division with models and images we talk about eggs and baskets. 18 ÷ 3 = We have 18 eggs and 3 baskets

Your turn 36 ÷ 6 =

From this we move onto repeated subtraction. 28 ÷ 4 =

42 ÷ 7 = Your Turn 42

Starting to chunk. 124 ÷ 4 = x 4 = Answer 31

Your Turn 87 ÷ 3 = 87

Knowing multiplication facts this can be developed further. 138 ÷ 6 = x 6 = x 6 = x 6 = Answer is 23

Your Turn 64 ÷ 4 = 64
