multiplication

How to teach ?

STEP 1

Understand multiplication as repeated addition(6,7,8 and 9 timestables)

Example : Count on in twos

Count on in threes

Example :

2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2

3 + 3 + 3 + 3 + 3 + 3 + 3 + 3 + 3

4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4

5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5

6…….

7…….

Multiplication with the highest product of 1000

Write the number sentences for the repeated addition and multiplication.

6 + 6 + 6 + 6 + 6 = 30

5 x 6 = 30

8 + 8 = 16

2 x 8 = 16

STEP 2

- USING THE NUMBER LINES

1× 6 = 18

4 x 3 = 12

Using Abacus

67 x 2 =

60 x 2 = 120 7 x 2= 14

Using Abacus

199 x 5 =

100 x 5 = 500 90 x 5 = 450 9 x 5 = 45

Using Abacus

236 x 4 =

200 x 4 = 80030 X 4 = 120 6 x 4 = 24
