Pick one trick per session
Do not try to learn every shortcut at once. Choose one topic, such as multiplying by 11, multiplying by 25, or exponent rules, and drill that one pattern first.
Do 10 untimed examples
Start slow enough to understand the pattern. For the 11s trick, try 23 x 11, 54 x 11, 68 x 11, and 79 x 11. Say the steps out loud until they feel automatic.
Do 20 timed examples
After the pattern is clear, add time pressure. The goal is not just to know the trick; the goal is to recognize it fast during a test.
Mix it into a general set
Once a trick is comfortable, practice it inside a mixed set. This is where students learn to spot which shortcut applies without being told.
Track misses by trick
- Missed 11s because of carrying
- Missed 25s because dividing by 4 was slow
- Missed exponent rules because multiplication and power-of-power got mixed up
Examples
- Session 1: practice ten 11s problems untimed, then twenty 11s problems timed.
- Session 2: practice multiplying by 25 using x100 divided by 4, then mix those into a timed set.
- Session 3: review misses and write the reason: carry mistake, slow division, or wrong shortcut.
