Printable math worksheet for measuring lengths using rulers.

Let’s go through each bar one by one. We’ll look at where the bar starts and where it ends on the ruler, then subtract to find the length.

Remember: The rulers are marked in inches, and we’re measuring from the left edge of the blue bar to the right edge.

1) Bar starts at 0, ends at 4 → Length = 4 - 0 = 4

2) Bar starts at 1, ends at 5 → Length = 5 - 1 = 4

3) Bar starts at 4, ends at 5.5 → Length = 5.5 - 4 = 1.5

4) Bar starts at 0, ends at 1 → Length = 1 - 0 = 1

5) Bar starts at 0, ends at 6 → Length = 6 - 0 = 6

6) Bar starts at 0, ends at 3 → Length = 3 - 0 = 3

7) Bar starts at 1, ends at 3 → Length = 3 - 1 = 2

8) Bar starts at 0, ends at 7 → Length = 7 - 0 = 7

9) Bar starts at 0, ends at 5 → Length = 5 - 0 = 5

10) Bar starts at 1, ends at 7.5 → Length = 7.5 - 1 = 6.5
