Choose the best unit for a length, and solve same-unit problems.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 63

We measure length in inches, feet, yards, and miles. An inch is about as long as a paper clip.
A foot is about as long as a big sub sandwich. A yard is about as long as a baseball bat. A mile is a long walk: about 20 minutes!
Pick the unit that makes sense. A pencil is about 7 inches, not 7 miles! A drive to the beach is about 200 miles, not 200 inches.
When every length is in the same unit, solve it like any story. A 20-foot rope minus 8 feet leaves 12 feet.
