FAQ
What is the compensating strategy for multiplying by a number near 100?⌄
For 6 × 98, compute 6 × 100 = 600, then subtract 6 × 2 = 12 (since 98 = 100 − 2), giving 600 − 12 = 588 — faster than decomposing into full tens and ones.
When is the near-100 strategy most efficient?⌄
It works best when the number is within 5 of 100 — the closer to 100, the smaller the adjustment and the faster the mental calculation.
How does this strategy build number flexibility?⌄
It teaches students to choose the most efficient decomposition rather than always using the same approach — a hallmark of strong number sense and mathematical flexibility.
