Observation:
Measurement is everywhere in our daily lives! We use it to understand size, weight, time, and value.
Learning About Measurement
Length Measurement:
We measure length using metric units:
| Unit | Symbol | Equivalent | Example |
|---|---|---|---|
| Millimeter | mm | 1/1000 of a meter | Thickness of a coin |
| Centimeter | cm | 1/100 of a meter | Width of a finger |
| Meter | m | Base unit | Height of a door |
| Kilometer | km | 1000 meters | Distance between cities |
Mass and Capacity:
We measure weight and volume using these units:
| Type | Unit | Symbol | Equivalent |
|---|---|---|---|
| Mass | Gram | g | Base unit |
| Kilogram | kg | 1000 grams | |
| Milligram | mg | 1/1000 of a gram | |
| Capacity | Milliliter | mL | 1/1000 of a liter |
| Liter | L | Base unit | |
| Kiloliter | kL | 1000 liters |
Time and Money:
Understanding time and money is essential for daily life:
- Time: 60 seconds = 1 minute, 60 minutes = 1 hour, 24 hours = 1 day
- Money: Count coins and bills, make change, calculate totals
- Geometry: Perimeter = sum of all sides, Area = length × width
