Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Before any arithmetic, ask which unit is smaller. Smaller units mean more of them, so the answer should be a bigger number than the start. Keep a reference row nearby for the first few sheets: 12 inches, 3 feet, 16 ounces, 4 quarts, 2 pints, 2 cups, 60 minutes. If 3 ft comes out as 48 in, the pound factor snuck in. Each pair keeps its own number.

Watch for: Kids multiply no matter which way the conversion goes, turning 48 in into 576 ft. Going to a bigger unit means fewer of them, so divide: 48 ÷ 12 = 4 ft. Kids mix up which factor goes with which pair, using 12 for pounds or 16 for feet. There are 16 ounces in a pound and 12 inches in a foot, and each pair keeps its own number.

Common questions about converting customary units

Which unit pairs show up on the sheet?

Feet and inches, yards and feet, pounds and ounces, gallons and quarts, quarts and pints, pints and cups, and hours and minutes. Every fourth grade item converts the larger unit to the smaller one, with a whole-number answer.

Does my child need the conversion facts memorized first?

It helps, but the sheet is also how they get memorized. Let your child use a reference list at the start. The goal is choosing the right factor and multiplying, and the facts stick with repetition.
