10 Steps to Multiplication Memorization

Emily is working on her multiplication tables this summer in preparation for school next year. Here is the plan we are using... (We are already up to the 3's and have skipped ahead and done the 11's)



1. Learn the 0’s
Any # times 0 is 0.

2. Learn the 1’s
Any # times 1 says itself.

3. Learn the 10’s
Count by 10’s - say aloud and write
10,20,30,40,50,60,70,80, 90,100, 110, 120

Practice the 10’s with a partner, and point to the answer on the paper.

4. Learn the 5’s
Count by 5’s - say aloud and write

5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60

Practice the 5’s with a partner, and point to the answer on the paper.


5. Learn the 2’s
Count by 2’s - say aloud and write

2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24,

Practice the 2’s with a partner, and point to the answer on the paper.


6. Learn the 3’s
Count by 3’s - say aloud and write

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36

Practice the 3’s with a partner, and point to the answer on the paper.


7. Learn the 11’s
Learn the trick - a # times 11 says itself twice.

For example: 5×11=55(This works up to 9×11)

11×11 is 11 with a 2 in the middle (121)

11×12 is 13 plus a 2 (132)- 11, 12, 13 plus a 2


8. Learn the Double Rhymes and 7×8
4×4 isn’t mean, 4×4 is sweet 16

6×6 pick up sticks, 6×6 is 36

7×7 feeling fine, 7×7 is 49

8×8 fell on the floor, 8×8 is 64

9×9 ate a ton, 9×9 is 81

12 x 12 give 4 more, 12×12 is 144

5, 6, 7, 8 - 56 is 7×8


9. Learn the 9’s

Learn the trick - 9×7 starts with 6 (it is 1 less than 7) 6+3 more = 9

The Answer is 63. (6 and 3, The # less than 7 and the # added to get to 9)

Kids can hold up 7 fingers, take 1 away to have 6. Then, count up 3 fingers to get 9.


10. This Leaves Only 8 Left to Memorize

Learn the remaining 8 by making flashcards.

4×6, 4×7, 4×8, 6×7, 6×12, 7×12, 8×12, 9×12

You may want to concentrate on 4×8, 6×7, 6×12 at the same time.

All the answers end in 2. (32, 42, 72)
