Measurement Story Problems
Solve measuring problems with all four operations.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 78
- Measuring problems use all four operations. Ava has 2 meters of ribbon and cuts off 45 centimeters. Make the units match first: 2 meters is 200 centimeters.
- Sharing is dividing. 1 liter of juice in 4 equal cups: 1 liter is 1,000 milliliters, and 1,000 divided by 4 is 250 milliliters each.
- Fractions with the same bottom number add like before. 3 fourths of a liter plus 2 fourths of a liter is 5 fourths of a liter.
Georgia's K-12 Mathematics Standards:
- 4.MDR.6.1 — Use the four operations to solve problems involving elapsed time to the nearest minute, intervals of time, metric measurements of liquid volumes, lengths, distances, and masses of objects, including problems involving fractions with like denominators, and also problems that require expressing measurements given in a larger unit in terms of a smaller unit, and expressing a smaller unit in terms of a larger unit based on the idea of equivalence.
