[quote=Anonymous]For addition and subtraction was just a lot of drills and flash cards. My daughter is a visual learner so for multiplication it's charts pasted around the house and in front of her seat in the car and drills, and flashcards.

The thing about multiplication is it only really comes down to 7 X 7. Teach them the tricks for 0, 1, 9, 10, and 11. Done in less than a day to master all these numbers. Then with respect to 2, 3, and 5 it's all about counting by those numbers - 2, 4, 6, 8 or 3, 6, 9, or 5, 10, 15, etc... which they did in K. Done in about 3-4 days to remind them multiplying is repeated addition and it's about counting by those numbers. Once 2 and 3 are mastered, 4, 6, and 8 are easy because you're doubling or doubling twice (for 8). Done in about 2 days because doubling or doubling twice is easy for kids. So that really only leaves you with 7 but since you know all the other numbers, you're only left with 7 X 7. A child can memorize 49 and be done. Once you get that it's just drill, drill drill for speed. It's easier than people realize and not as daunting as thinking there is so much to memorize.

Another trick for 7 X 7 that I teach is if you know 4X7 and 3X7 (5 and 3 are easier for kids to remember) and you add the answers, then you get 7 X 7 OR if you know 5X7 and 2X7 and you add then you get 7 X 7. I think being really good at addition makes learning multiplication take less than a week because you can employ a lot of math hacks. There is nothing wrong with math hacks. You do them enough times you start to memorize answers without the hacks.

With division, all I had to say was it was the reverse of multiplication and she got it without much drilling.
