This math chapter workbook on "Customary Length, Weight, and Capacity" introduces students to the basic units of measurement commonly used in the United States. For length, this includes inches, feet, yards, and miles, teaching students how to measure objects and how to convert between these units. In weight, worksheets cover ounces, pounds, and tons. For capacity, the workbook explores cups, pints, quarts, and gallons. Additionally, real-world problems and word problems aid students in understanding when and how to use these measurements in everyday life. Suitable activities to go with this workbook would be hands-on activities, such as using rulers, scales, and measuring cups, to help students gain practical experience.

Young children often become confused between customary English measurements and the metric system due to differences in unit names, magnitudes, and conversion rates. The metric system's base-10 structure is more straightforward for mathematical conversion, but children may not yet be comfortable with decimal-based math. Working on the systems in separate third-grade workbooks helps kids get comfortable with their differences.
