Customary Measurement is a Grade 4 math worksheet that helps students choose appropriate U.S. customary units for length, distance, capacity, mass, and weight. Through multiple-choice, multiple-select, and open-ended questions, students identify units such as feet, miles, gallons, ounces, pounds, inches, and cups; distinguish customary units from metric units; and connect units to familiar objects and situations. The worksheet also asks students to estimate reasonable measurements, select all applicable measurement attributes, interpret a ruler image, and recognize that a measuring tool must begin at zero. These tasks build practical unit-selection and measurement-reasoning skills rather than focusing only on memorizing unit names. This free printable worksheet is designed for Grade 4 mathematics instruction, independent practice, review, or assessment, and includes a complete answer key for efficient checking.

This Grade 4 worksheet practices choosing appropriate U.S. customary units for length, distance, capacity, mass, and weight. Its multiple-choice, multiple-select, and open-ended items ask students to classify customary versus metric units, match units to real-world quantities, estimate reasonable measurements, and interpret a ruler that must start at zero.
Introduce the worksheet by sorting familiar examples—such as a trip to a store, water in a container, or the weight of a book—by the attribute being measured and the most suitable customary unit. Then have students explain their choices for the multiple-choice items, model why a ruler reading must begin at zero, and use the multiple-select questions to review several valid units or attributes at once.
Students may confuse units by attribute, such as choosing pounds for distance, gallons for mass, or ounces for a long measurement. Watch for students selecting metric units such as grams, liters, or kilometers when asked for customary units, choosing an unrealistic capacity or distance, or accepting the toothpick measurement even though the ruler does not begin at zero.
The worksheet is available as a printable PDF and as a digital quiz on Wayground, with a complete answer key for all question types. Printable submissions can be graded by scanning student work with the Wayground for Teachers app, while the digital version can be assigned for online completion and grading.
Use the worksheet’s Advanced Settings to adjust font spacing and font size so the unit choices, real-world scenarios, and ruler item are easier to read. You can also enable a dyslexia-friendly font or translate the worksheet into another language to support access to the measurement vocabulary.
