For another lark, go to Kahn Academy and check out how he teaches arithmetic up to third grade.
You have to look really hard to find addition and multiplication tables. They’re there, with the rather lame comment that they’re good to know.
But, they are not in his main stream, which depends on gimmicks to figure out the answer, instead of just rote memorization of the tables (which is good for the brain, as well).
As an example, I know my multiplication table just fine through 12. But, something went wrong in the second grade, and my addition was terrible. I depended for years on tricks: to add three, count up very quickly on the three points of the numeral 3. Same for four. For five, count one point twice.
I was in trouble at adding seven, because I couldn’t do something like add three twice!
I was shocked that Kahn uses tricks like that.
