Description

"Area of ​​Parallelogram" Area of ​​Polygon PPT Courseware 2

The picture below is a parallelogram. Each square in the figure represents 1 square centimeter. Please use the method of counting squares to find out its area. (Anything less than one square will be calculated as half a square.)

Observe the two parallelograms below. Are their bases equal? High equal? Are the areas equal? Based on these two figures, think about it, who does the area relate to?

Group cooperative learning:

1. Is the area of ​​the original parallelogram equal to the area of ​​the resulting rectangle?

2. Is the base of the parallelogram equal to the length of the rectangle?

3. Is the height of the parallelogram equal to the width of the resulting rectangle?

4. Can you tell the formula for the area of ​​a parallelogram?

Operational exercises

Ask the students to use a ruler to measure the base and height of the parallelogram you made. (Measurements kept to whole centimeters). and calculate its area.

This courseware provides a comprehensive introduction to the area of ​​parallelograms through small games and exercises, which improves students' interest in learning and helps students better understand and remember the knowledge points of the area of ​​polygons. It is a good classroom teaching courseware.
