We are still cooking the magic in the way!
Problem
Memorizing the 9 times table is difficult for many students.
Solution
Hold up 10 fingers. For 9×n, fold down the nth finger. Fingers left of fold = tens, right = ones.
Benefit
Visual method that works for all single-digit multiplications with 9.
Example
9 × 3:
Fold down 3rd finger → 2 fingers left, 7 fingers right → 27
9 × 7:
Fold down 7th finger → 6 fingers left, 3 fingers right → 63
