4th grade math · Unit 3: Division

Partial quotients

What this lesson shows

465 ÷ 3 by taking away easy chunks (100 groups, 50 groups) and adding them up.

The worked example

The lesson works this one step by step: 465 ÷ 3. Then your kid tries one like it on paper.

The steps

  1. Write easy facts
  2. Take away the biggest chunk that fits
  3. Subtract, and repeat
  4. Add up the groups

Helping at home

Write easy facts for the number you divide by first. Take away the biggest chunk that fits, subtract, and repeat. Any chunk the kid knows is fine. Add up the groups at the end, then check by multiplying back.

If your kid gets stuck

Write easy facts first: 100, 50, 10, and 5 groups.
