Understanding Area Measurement with Grid Paper

The video tutorial explains how to measure the area of shapes using different units of measure. It emphasizes the importance of using keys in picture graphs to count items accurately and demonstrates how to count square units on grid paper to determine the area of a shape. The tutorial also highlights the significance of grid paper size in measuring area and provides examples using square centimeters and square inches. The lesson concludes with a review of the key concepts covered.
