Lesson Summary:

In this basic area lesson, students learn what area is and how to calculate it for simple shapes such as rectangles, parallelograms, and triangles. They also learn the units of area and how to measure height perpendicular to the base. Students are introduced to formulas for calculating area and given examples to practice with. The lesson emphasizes the importance of measuring properly for accurate results and includes interesting facts, such as how all triangles with the same base and height have the same area.

Lesson Description:

Basic math of area, units, rectangle, parallelogram, triangle
