5th grade math · Unit 4: Dividing whole numbers

Partial quotients, two-digit divisors

What this lesson shows

6,924 ÷ 15 by taking away 400 groups, 60 groups, then 1 more: 461 and 9 fifteenths.

The worked example

The lesson works this one step by step: 6,924 ÷ 15. Then your kid tries one like it on paper.

The steps

  1. Write easy facts
  2. Take a chunk for each place
  3. Add up the groups
  4. Write what is left as a fraction

Helping at home

Write easy facts for 100, 10, and 1 group of the divisor. Take away the most hundreds of groups that fit, then tens, then ones, and keep the groups in their own column. Add them up, and write what is left as a fraction of the divisor.

If your kid gets stuck

Write the easy facts first. Write what is left as a fraction.
