Metric prefixes are important when we talk about measurements in math, especially in Year 8. They help us understand and change between different units of measurement easily.

These prefixes are added to basic units, like meters (m) or grams (g), to show bigger or smaller amounts of these units.

Common Metric Prefixes:

1. Kilo- (k): Means 1,000.

   • Example: 1 kilometer (km) = 1,000 meters (m).

2. Hecto- (h): Means 100.

   • Example: 1 hectometer (hm) = 100 meters (m).

3. Deca- (da): Means 10.

   • Example: 1 decameter (dam) = 10 meters (m).

4. Deci- (d): Means 0.1.

   • Example: 1 decimeter (dm) = 0.1 meters (m).

5. Centi- (c): Means 0.01.

   • Example: 1 centimeter (cm) = 0.01 meters (m).

6. Milli- (m): Means 0.001.

   • Example: 1 millimeter (mm) = 0.001 meters (m).

Why Metric Prefixes Matter:

Knowing these prefixes helps students understand big and small measurements in an organized way.

For example, knowing that 1 kilogram (kg) is the same as 1,000 grams (g) can be really useful in everyday tasks like cooking or making things.

Metric prefixes are not just important for math problems. They also help us share measurements clearly in science, engineering, and daily life.
