About this worksheet
Measuring length starts with counting equal units laid end to end. A bar that lines up with 7 cubes, with no gaps or overlaps, is 7 cubes long.
Measuring with cubes before a ruler shows what a length number means: how many units fit. A ruler is the same idea with the units printed on it.

The common mistake
What it looks like: Counting a cube twice, or skipping one, in a long row.
Why it happens: The cubes all look alike, so it's easy to lose your place.
How to fix it: Put a small pencil tick on each cube as you count it.
