5th grade math · Unit 12: Converting measurements

Chains of units

What this lesson shows

Minutes in a week: 60 × 24 × 7, one unit at a time.

The worked example

The lesson works this one step by step: 1 week to minutes. Then your kid tries one like it on paper.

The steps

  1. No one fact
  2. One link at a time
  3. Multiply the facts

Helping at home

When no single fact gets you there, go down a chain of units one link at a time, multiplying by each fact: a week is 7 days, a day is 24 hours, an hour is 60 minutes.

If your kid gets stuck

One unit at a time.
