Progressively harder doubling and halving; from teens, to 2-digit multiples of 5 to 3-digit multiples of 10.

This is where we make real headway with learning the 2x, 5x and 10x tables. Make sure they are recited as a whole and not just saying the answers (which is just counting up).

More multiplying by 10 and 100. Probably one of our easier sets of pages.

Doubling is coming up again. This time it's all multiples of 5. (Just remember that double 5 is 10.)
