Fourth graders change a length from one unit to another in the same system, such as yards to feet or kilometers to meters. Each line on this worksheet gives a measure and the unit to write it in, and your child writes the number on the line.
Sheets 1 to 3 use yards, feet, inches and miles; sheets 4 to 6 use kilometers, meters, centimeters and millimeters. Going to a smaller unit means multiplying; going to a larger unit means dividing, and every answer is a whole number.
What your child will learn
Change a larger length unit to a smaller one
Change a smaller length unit to a larger one
Use the conversion fact for each pair of units
Common Core standard: 4.MD.A.1
Worked example
3 ft = 36 in, because 1 ft = 12 in and 3 × 12 = 36.
Common mistake
Writing 4 feet as 16 inches by using the wrong conversion fact.
