Ordering length challenges students to do two things at once: Measure and Compare. It is the next logical step after learning to use non-standard units.
The “1-2-3” Method In this worksheet, counting the units is just the first step.
- Step 1: Measure the three carrots using the blocks provided.
- Step 2: Compare the numbers (e.g., 2 blocks, 4 blocks, 6 blocks).
- Step 3: Write “1” for the shortest, “2” for the medium, and “3” for the longest.
This activity reinforces number sense and visual discrimination in Preschool Math.
