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)

Nice. So logical. Our school uses Everyday Math too (it sucks) so this is great for future reference.

OP, our school supplements with Rocket Math. DS is younger so we are only working on addition now, but you could check out the website. Basically your child practices small sets of facts for short periods of time until they master them and move on to the next set. The only complaint I have is that there are very specific rules for implementing it "correctly" and achieving mastery that don't actually seem to have been empirically tested. My kid is kind of a slow processor and writer so if the school were following the actual rules and time limits for him he would still be practicing copying numbers (what you do before you learn facts). Luckily they played around with the timing and writing requirements for him and he is almost all the way through the addition facts. He is definitely mastering them even with the changes.

There is also a Rocket Math app. It is useless for us because there is no way to adjust the timing requirements, but it might be great for other kids.
