Teach him in this order

0
1
10
2 (first teach him to count by 2's)
5 (first teach him to count by 5's)
4 (teach him 4 x 3 is really 2x3=6x2=12) (concept not memorization) (but if he can memorize great)
9 (teach the trick for 9's) 9x5= (first number is 5-1=4, 2nd number is 4+whatever equals nine 4+5=9) answer is 45 (the two numbers always equal 9)
I will do 1 more 9 for you 9x8 = (first number is 8-1=7, 2nd number is 7+whatever equals nine 7+2) answer 72 (7+2=9)
There is also a finger trick you can learn from the internet.

Memorize 1x1, 2x2, 3x3, 4x4... it on the diagonal and it is important when you do square roots.

11, they are easy 11x4 = 44, you only need to memorize 11x11 and 11x12

You are left with 3, 6, 7, 8, 12 but if you mark off all the 0, 1, 2, 4, 5, 9, 10, 11 and the diagonal you will see you don't have that much to memorize.

The only fun trick I have is 8x8 is 64... I ate and ate and got sick (six) on the floor (four)
