FAQ
What does 'multiply in parts' mean as a strategy in 5th grade math?⌄
Multiplying in parts means decomposing one or both factors by place value — for example, 34 × 6 = (30 × 6) + (4 × 6) = 180 + 24 = 204 — and then adding the partial products.
How does multiplying in parts help 5th graders understand the standard algorithm?⌄
The standard algorithm performs the same partial products but in a compressed format — students who first practice the expanded parts approach develop stronger conceptual understanding of why the algorithm works.
When is multiply in parts a more efficient strategy than the standard algorithm for 5th graders?⌄
For mental math and estimation, multiplying in parts using round numbers is often faster — for example, 99 × 7 = (100 × 7) − (1 × 7) = 700 − 7 = 693 is quicker than the written algorithm.
