Here are some tips for Multiplication Facts Strategies, which aligns with California state standards:

**Multiplication Facts Strategies**

3 × 2 = 3 + 3 = 6Multiply by 5

5 × 2 = 5 + 5 = 10

8 × 2 = 8 + 8 = 16

Use the

Odd numbers multiplied by 5 end in "5" and even numbers multiplied by 5 end in "0".

3 × 5 When the minute hand is on 3, it is 15 minutes after the hour. 3 × 5 = 15

5 × 5 When the minute hand is on 5, it is 25 minutes after the hour. 5 × 5 = 25

8 × 5 When the minute hand is on 8, it is 40 minutes after the hour. 8 × 5 = 40

Skip count For 3 × 5, 5, 10, 15, ... 3 × 5 = 15 For 5 × 5, 5, 10, 15, 20, 25, ... 5 × 5 = 25 For 8 × 5, 5, 10, 15, 20, 25, 30, 35, 40, ... 8 × 5 = 40

Multiply by 10

** Add a zero to the end** of the number.

3 × 10 = 30Multiply by 9

8 × 10 = 80

123 × 10 = 1230

Multiply by 4Bend the finger of the number you want to multiply. Then count the number of fingers on both sides of the bent finger to get the answer.

Note: For multiples of 9, the digits add up to 9.

For 3 × 9, bend Finger 3.

3 × 9 = 27

For 7 × 9, bend Finger 7.

7 × 9 = 63

3 × 9 = 27 → 2 + 7 = 9 7 × 9 = 63 → 6 + 3 = 9

Multiply by 3

Doubling once Doubling twice For 3 × 4, 3 × 2 = 6

or

3 + 3 = 6→ 6 × 2 = 12

or

6 + 6 = 123 × 4 = 12 For 5 × 4, 5 × 2 = 10

or

5 + 5 = 10→ 10 × 2 = 20

or

10 + 10 = 205 × 4 = 20 For 8 × 4, 8 × 2 = 16

or

8 + 8 = 16→ 16 × 2 = 32

or

16 + 16 = 328 × 4 = 32

Multiply by 6

Skip count For 3 × 3, 3, 6, 9, ... 3 × 3 = 9 For 5 × 3, 3, 6, 9, 12, 15, ... 5 × 3 = 15 For 8 × 3, 3, 6, 9, 12, 15, 18, 21, 24, ... 8 × 3 = 24

2 × 6 = 2 × 5 + 2 = + 2 × 6 = 10 + 2 2 × 6 = 12

3 × 6 = 3 × 5 + 3 = + 3 × 6 = 15 + 3 3 × 6 = 18

5 × 6 = 5 × 5 + 5 = + 5 × 6 = 25 + 5 5 × 6 = 30
