Mini Lesson
Measurement means finding the size of something using a standard unit. We measure length in millimeters (mm), centimeters (cm), meters (m), or kilometers (km). We measure mass in grams (g) or kilograms (kg). We measure capacity in milliliters (mL) or liters (L).
Measurement Units
- Length: 10 mm = 1 cm, 100 cm = 1 m, 1,000 m = 1 km.
- Mass: 1,000 g = 1 kg. Use a balance or a kitchen scale.
- Capacity: 1,000 mL = 1 L. Use a measuring cup.
- Area: length x width (in square units, e.g. cm squared).
- Perimeter: add all the sides together.
Choosing the Right Tool
- Ruler: best for measuring objects up to 30 cm.
- Tape measure: best for longer objects or curved surfaces.
- Kitchen scale: for measuring mass of food items.
- Measuring cup: for measuring liquids.
