Bigger Units in Smaller Units

1 m = 100 cm, 1 km = 1,000 m, 1 kg = 1,000 g, 1 L = 1,000 mL.

Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.

What children learn in Level 76

A meter is 100 centimeters. So 2 meters is 200 centimeters, and 3 meters is 300. A table keeps track.
Each row adds 100 more centimeters. 4 meters is 4 times 100: 400 centimeters.
Kilometers, kilograms, and liters each hold 1,000 of the smaller unit.

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.
