Peter Duveen says: >Therefore, 1/8 x 1/8 = 1/64, which is, of course, smaller than 1/8.
1/8 of *anything* will result in something smaller that the multiplicand. Why not go with a simpler example. Should one conclude wrongly that both multiplier and multiplicand should be less than 1 to get the desired effect?
Anyway, if that works, fine. Going back to the original posting, I thought a full blown animation seemed a bit much. Animations have a mixed bag rep for math teaching purposes.
I opined earlier too, that being able to see multiplication in a sloped line was a fine way to address the issue.
