FAQ
What is the quickest mental strategy for multiplying by a multiple of 10?⌄
Multiply the non-zero digits as if they were single-digit facts, then append one zero — so 6 × 40 = 6 × 4 × 10 = 24 × 10 = 240.
How does this skill support multi-digit multiplication?⌄
Every partial product in multi-digit column multiplication involves multiplying by a multiple of 10 — mastering this mental step makes the algorithm faster and more accurate.
Is multiplying by whole tens connected to understanding powers of 10?⌄
Yes — multiplying by 10, 20, 30... reinforces that each place value is 10 times the one below it, directly supporting 4th grade place value standards.
