I don’t use the same tricks as you, but I agree each number has its own set of tricks. Times 2 is basically like addition, just doubling. 9’s you only have to visualize half the numbers, because the other half are exactly the reverse. The 9 tables has 18, 81, 27, 72, 36, 63, 45, and 54. The first number is 1 less than what you are multiplying. 9×3, the first number starts with a 2, so 27. Your double check is 2+7=9. In fact, that’s all you really need to remember with 9, the two numbers added equal 9, and starts with 1 less than the number. I never understood why people do that subtraction thing with the 9’s. Subtraction isn’t easy in my opinion, but that’s my opinion, and may be easy for others. 5’s are easy, because we count in 5’s from young ages. 4’s are exactly like 2’s you just double twice. You can do it with 8 also, but depends how big the number is if it gets difficult for someone. Some rhyme like 6×8 is 48, and that covers the 6 and the 8. You only need to remember half the table, because you can always flip the equation around. If you remember 3×8 you know 8×3. I don’t remember memorizing times tables. I remember my tricks for each equation. Edit: I think it’s probably better not to do it as a huge table of numbers and better to just do 2’s one week, then 3’s the next week, etc. That’s how I remember it from my own childhood.
