Compare and order up to three things by length.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 55
- To compare lengths, line things up at one end. Then see which one goes farther. The pencil is longer than the crayon.
- The crayon is shorter than the pencil. Shorter means it doesn't reach as far.
- With three things, find the longest and the shortest. In order from shortest to longest: key, crayon, pencil.
- Your turn! Tap them in order, from shortest to longest.
- Try it with a grown-up! Line up three shoes from your home. Which is the longest?
Georgia's K-12 Mathematics Standards:
