Our Area of Triangles and More Lesson Plan equips students to identify and use the formula for the area of triangles, trapezoids, and parallelograms such as the rhombus and other quadrilaterals. This lesson also briefly reviews the application of the commutative property of multiplication in these formulas. During this lesson, students are asked to complete a fun and interactive activity with a partner in which they create their own examples of polygons and then determine the perimeter and area of each using straws to create 3-D models. Students are also asked to demonstrate their understanding by finding the area of a given polygon, matching polygons with their descriptions, and more.
At the end of the lesson, students will be able to identify and use the formula for the area of triangles, trapezoids, and parallelograms such as the rhombus and other quadrilaterals.
