FAQ
How does 3 × 3-digit multiplication extend the standard algorithm beyond 2-digit multipliers?⌄
A third multiplication pass is added (for the hundreds digit of the second factor), shifted two places to the left, producing a third partial product row that must be added to the first two.
What placeholder strategy prevents alignment errors in 3 × 3-digit problems?⌄
Place a zero in the ones position of the second row and two zeros in the ones and tens positions of the third row — these placeholders ensure each partial product is correctly scaled.
Is 3-digit by 3-digit multiplication required by 4th grade Common Core?⌄
CCSS 4.NBT.B.5 covers up to 4-digit by 1-digit and 2-digit by 2-digit — 3 × 3-digit extends beyond the core standard and is appropriate as an enrichment challenge for advanced students.
