About these worksheets
Students work with both American customary and metric measurement systems side by side. Worksheets include measuring objects in both inches and centimeters, estimating lengths using both systems, filling in conversion tables, and balancing equations with mixed units. These activities help students see the relationship between the two measurement systems. Aligned with second through fourth grade.
2md4
- Practice measuring the same object in both inches and centimeters
- Read a ruler to the nearest half inch and to the nearest centimeter
- See that the same length gives a different number depending on the unit used
2md2
- Read a ruler to find the width of an object in inches.
- Read a ruler to find the width of an object in centimeters.
- Use measurement words like wider, narrower, longer, and shorter to describe the comparison.
2md2
- Measure the width and height of a block using a ruler.
- Read ruler marks to write measurements in inches and in centimeters.
- Use words like greater than and less than to describe measurement comparisons.
2md3
- Choose whether inches, feet, centimeters, or meters makes the most sense for a length in a word problem.
- Use what you know about common objects to make a reasonable estimate of a length.
- Tell the difference between small lengths and longer distances so you don’t pick a unit that’s way too big or too small.
4md1
- Convert between larger and smaller units of length, weight, and liquid volume.
- Use a conversion table to find the matching value in a different unit.
- Multiply or divide by a conversion factor to fill in missing measurements.
- Practice balancing measurement equations by figuring out the missing amount that makes both sides equal.
- Practice writing the correct abbreviations for common U.S. customary units like inches, feet, yards, and miles.
- Practice writing the correct abbreviations for common weight and capacity units like ounces, pounds, cups, pints, quarts, and gallons.
- Practice writing the correct abbreviations for metric units like millimeters, centimeters, meters, kilometers, milliliters, and liters.
- Learn to match a unit name to its standard abbreviation without mixing up similar-looking abbreviations (like m vs mi or oz vs lb).
- Practice reading common measurement abbreviations and writing the full unit name.
- Learn the correct spelling of standard and metric measurement units.
- Recognize similar-looking abbreviations and match each one to the right unit.
