Decompose a Kilogram into Grams
Decompose a Kilogram into Grams is a Grade 3 math skill from Eureka Math demonstrating the fundamental metric weight relationship: 1 kilogram = 1,000 grams. A kilogram can also be thought of as 10 equal parts of 100 grams each. Students practice decomposing kilogram amounts into grams using this relationship. For example, 3 kg = 3,000 g. This skill builds metric measurement fluency and introduces students to the base-ten structure of the metric system, connecting place value knowledge to real-world measurement.
Key Concepts
A kilogram can be decomposed into 10 equal parts, with each part weighing 100 grams. This demonstrates the fundamental relationship between kilograms (kg) and grams (g). $$1 \text{ kg} = 10 \times 100 \text{ g} = 1000 \text{ g}$$.
Common Questions
How many grams are in one kilogram?
1 kilogram (kg) = 1,000 grams (g). This is the fundamental metric weight conversion.
How can you decompose 1 kilogram into smaller parts?
1 kilogram = 10 equal parts of 100 grams each. So 1 kg = 10 × 100 g = 1,000 g.
How do you convert kilograms to grams?
Multiply the number of kilograms by 1,000. For example, 4 kg = 4 × 1,000 = 4,000 g.
How does the metric system's base-ten structure appear in kilograms and grams?
1 kg = 1,000 g = 10 × 100 g. The relationship between kg and g uses factors of 10 and 100, consistent with the metric system's decimal structure.
