Description:
Just like Fast Addition, but does the math facts in reverse.
Research suggests that learning 9s, then 8s, then 7s, and so on
may be more efficient than learning 1s, then 2s, then 3s, and so on. The
reason is that you'll reinforce learning of the hardest materials from
start until end.
Adaptive Learning Progression: Develops your 9's through 1's separately, then combines them later. Speed is essential. |
