Weight is how we measure how heavy something is. In third grade, we usually use grams (g) and kilograms (kg). Grams are for lighter things, like a paperclip, and kilograms are for heavier things, like a bag of apples. Remember, 1 kilogram is equal to 1000 grams! Weight measurement helps us compare and understand the heaviness of different objects.
Match the word with its definition:
| Word | Definition |
|---|---|
| Kilogram | A. The amount of matter in an object |
| Gram | B. A tool used to measure weight |
| Weight | C. A unit of measurement equal to 1000 grams |
| Scale | D. A unit of measurement for smaller objects |
| Mass | E. How heavy something is |
