1. Converting Units of Length Grade 4 Mathematics - MATATAG Curriculum

2. Introduction - Understanding different units of length is important in daily life. - The metric system is the standard system of measurement used globally.

3. Basic Units of Length in the Metric System - Millimeter (mm) - Centimeter (cm) - Meter (m) - Kilometer (km) - Each unit represents different lengths used for various measurements.

4. Relationships Between Units - 1 meter = 100 centimeters - 1 meter = 1,000 millimeters - 1 kilometer = 1,000 meters - These conversions help in measuring objects of different sizes.

5. Converting Larger Units to Smaller Units - To convert meters to centimeters, multiply by 100. - To convert meters to millimeters, multiply by 1,000. Example: 5 meters = 5 × 100 = 500 centimeters.

6. Converting Smaller Units to Larger Units - To convert centimeters to meters, divide by 100. - To convert millimeters to meters, divide by 1,000. Example: 250 centimeters = 250 ÷ 100 = 2.5 meters.

7. Practice Problems Solve the following: 1. Convert 3 kilometers to meters. 2. Convert 1,500 millimeters to meters. 3. Convert 75 centimeters to meters.

8. Word Problems 1. A ribbon is 2.5 meters long. How many centimeters is that? 2. A road is 3 kilometers long. How many meters is that?

9. Summary - We use metric units like mm, cm, m, and km. - Convert larger units to smaller by multiplying. - Convert smaller units to larger by dividing. - Practice conversions in real-life situations.
