Worksheet Preview
Longer, shorter, and how long
Measurement starts with comparing (longer/shorter) and ordering by length, then measuring with same-size units like cubes or paper clips. Two rules matter: line up the ends to compare, and leave no gaps when measuring.
How to use it
Compare and measure real objects at home or in class. Builds toward estimating length in 2nd grade.
👩🏫 Teacher note
When comparing, line up one end of each object. When measuring with units (cubes, paper clips), there must be no gaps or overlaps. This builds toward rulers.
🏠 Parent note
Compare real objects at home — line up the ends and ask 'Which is longer?' Then measure with paper clips.
Common Mistakes to Watch For
- Not lining up the ends when comparing
- Leaving gaps between units when measuring
