About these worksheets
Students practice measuring lengths using American customary units. Worksheets include reading rulers in inches, estimating distances, choosing appropriate units, converting between inches, feet, yards, and miles, adding and subtracting measurements in feet and inches, and working with mixed unit conversions. Resources span second through fifth grade standards.
Measuring and Showing Data
- Measure the length of an object using a ruler and standard units.
- Write down measurements clearly so they can be compared.
- Make a line plot to show a set of measurements.
Estimating Length (American)
- Get better at making a reasonable guess for how long an object is without measuring it.
- Choose the best length from a few options by comparing what you see to familiar sizes (like an inch, foot, or yard).
- Decide which unit makes sense for an object’s length (inches, feet, or yards).
- Use benchmark lengths to tell when an estimate is too short or too long.
Determining Appropriate Measurement (American)
- Choose whether inches, feet, yards, or miles makes the most sense for a given distance.
- Use what you know about common objects and places to make a reasonable estimate of a length.
- Explain why one unit is more appropriate than another for measuring a specific distance.
Converting American Lengths
- Convert between inches, feet, yards, and miles using the right conversion facts.
- Multiply or divide by conversion factors to change a measurement to a different unit.
