1) Multiplying numbers can be done by breaking them into simpler factors and distributing multiplication across addition. 2) Doubling multiplication tables allows calculating unknown products, like doubling the 6 times table to find 7 x 12. 3) Using multiples of 10 near the numbers being multiplied allows calculating the product without fully multiplying, like using 8 x 20 to find 8 x 19.

1. MULTIPLICATION BY: ABHA ARORA

3. Multiplication by breaking numbers 4 x 7

4. Break 7 as (5 + 2)

5. 4 x 2 = 8 4 x 5 = 20

8. 10 x 2 = 20 2x 4 = 4

18. Using multiples of 10 to multiply other numbers 8 x 19 = ? 8 x 20 =160 - 8 1 5 2
