How to do it
- Find the fact for the two units.
- Divide by the number of small units in one big unit.
- Write any leftover in the small unit or as a fraction.
Teaching tip
A leftover of 6 inches is 6/12 of a foot. Simplifying it to 1/2 is a good extra step. This sheet is aligned with Common Core 5.MD.A.1.
About this worksheet
Customary length, weight, liquid volume and time to change from small units to big units, with the facts printed at the top. Fewer has 10 that divide evenly, Standard has 12 with leftovers, and More has 12 that include mixed numbers, like 168 in = 4 2/3 yd. Includes an answer key.
What kids practice
In 4th grade, students changed big units to small units by multiplying, like 3 ft = 36 in. Now they go both ways. Changing small units to big units means dividing, like 48 in = 4 ft, and leftovers can be written in the small unit or as a fraction, like 30 in = 2 ft 6 in = 2 1/2 ft. Metric units go by powers of 10, so converting just moves the digits, like 250 cm = 2.5 m. Students also compare measurements in different units and solve multi-step problems by converting first so the units match.
Watch for
- Multiplying when going from small units to big units.
- Writing a remainder as a decimal, like 30 in = 2.6 ft.
- Using the wrong fact, like 10 inches in a foot.
- Moving the digits the wrong number of places in metric conversions.
- Adding or subtracting amounts in different units without converting first.
It's free to print, with Fewer, Standard or More on the page and an answer key. See the full converting units guide for 5th grade.
