2nd grade math · Unit 5: Equal parts and time

Minutes, hours, days, and weeks

What this lesson shows

60 minutes make an hour, 24 hours a day, 7 days a week, and 12 months a year. Then pick the unit that fits: brushing teeth takes minutes, a trip takes days.

The worked example

The lesson works this one step by step: brushing your teeth (question 1). Then your kid tries one like it on paper.

The steps

  1. 60 seconds = 1 minute
  2. 60 minutes = 1 hour
  3. 24 hours = 1 day
  4. 7 days = 1 week
  5. 12 months = 1 year

Helping at home

Read each question aloud. Before picking a unit, ask: is it over in a blink, in a few minutes, by tonight, or does it take many days? Check the answer by saying it: "20 hours for lunch" sounds silly.

If your kid gets stuck

Say it with the unit. Does it sound right?

Watch it with Lux
