Measure and Estimate Length

Learners measure with rulers in inches and centimeters (starting at 0, or finding the length when an object starts elsewhere), choose tools such as yardsticks, meter sticks and measuring tapes, estimate lengths with benchmarks, explain why smaller units give bigger numbers, and find how much longer one object is than another.

  • 3 lessons
  • About 60 minutes
  • Length check: 8 questions
  • Ways to answer: choose an answer, estimate, match pairs, type a number, place on a number line and sort into groups
