Metric units help us measure things like length, weight, and volume! Choosing the right unit is like picking the perfect pair of shoesâit has to fit just right for the job you're doing. đ
First comes length, then comes weight, and finally comes volume. Letâs learn how to pick the best metric unit step by step!
For length:
- Use millimeters (mm) for tiny things like an
ant.
- Use centimeters (cm) for small things like a
pencil.
- Use meters (m) for big things like your
room.
- Use kilometers (km) for really big distances
like from home to school.
For weight:
- Use grams (g) for light things like a
feather.
- Use kilograms (kg) for heavier things like a
backpack.
For volume:
- Use milliliters (mL) for small amounts like
water in a spoon.
- Use liters (L) for bigger amounts like juice
in a bottle.
What unit should we use to measure the length of a soccer field?
Hmm⌠A soccer field is very long, so we need a BIG unit. That means we use kilometers (km) or meters (m). Since it's not as far as driving
across town, the best choice is meters (m)!
1. Make it fun! Use toys or snacks to practice measuring.
2. Sing along: âMillimeters are teeny-weeny, centimeters are small, meters are tall, kilometers
cover it all!â
3. Explore together: Measure objects around the house and ask, âWhat unit fits best?â
4. Celebrate every winâbig or small!
