Practice Length Measurement in Math

Use these practice problems to test your method after reviewing the concept explanation and worked examples.

Quick Recap

Measuring how long something is using standard units (inches, centimeters, feet, meters) or non-standard units (paper clips, hand spans), by comparing the object's length to repeated copies of the chosen unit laid end to end.

Measuring length is like asking 'how many of this unit fit end-to-end along the object?' Lay paper clips along a pencil—the number of clips is its length in paper-clip units.

Example 1

easy
A pencil is measured using paper clips as units. It takes 5 paper clips placed end to end to match the length of the pencil. How long is the pencil in paper clip units?

Example 2

medium
A bookshelf is 36 inches long. A book is 12 inches wide. How many books can fit side by side on the shelf?

Example 3

medium
Convert 3.5 km to meters, then to centimeters.

Example 4

easy
A worm is 4 cubes long and a caterpillar is 7 cubes long. How much longer is the caterpillar?

Example 5

medium
A table is 48 inches long. A chair is 16 inches wide. How many chairs can line up along the table?
