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

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
