AIM: How is area measured in Metric ?

This lesson focuses on measuring area using square units in the metric system. Students will learn how to use a meter stick to measure length in meters, centimeters, and millimeters. The lesson covers formulas for calculating the area of rectangles, providing various examples with dimensions provided in centimeters and millimeters. Real-world applications of area measurement in fields like real estate and carpet installation will be discussed. Students will have opportunities for classwork and homework to reinforce their understanding through practical calculations.
