Measurement Conversions — Intro

How the lesson starts: Measurement Conversions — Intro

  1. Coach Benny's Tiny Games

    Hi, sports fan! Coach Benny the beaver runs the Tiny Games for toy animals. He measures jumps in feet, but the judges want inches! Let's help him change units.

  2. 3 feet in inches

    Frog jumps 3 feet! Each foot is 12 inches. Hop 12 for each foot, three times: 12, 24, 36. So 3 feet = 36 inches. That's 3 × 12.

  3. A 6-hour snail race

    The snail race lasts 6 hours! How many minutes is that? The rule: 1 hour = 60 minutes. So 6 hours is 6 × 60. 6 × 6 = 36, so 6 × 60 = 360 minutes! Watch out: small units mean a bigger number, so multiply.
