Introduction to Polygons

This resource provides 5 different worksheets on the topic of polygons and symmetry. These worksheets cover rotational symmetry, lines of symmetry, symmetry of regular polygons, special quadiralaterals, and polygon transformation. The...

Arithmetic and geometric sequences are linear and geometric patterns. Help pupils understand the relationship and see the connection with an activity that asks them to write the rules and classify the patterns correctly. A sorting...

Show your class that finding angle measures is a regular calculation with a resource that provides 12 problems dealing with the measures of angles in regular polygons. Pupils use formulas for the sum of measures of angles in a polygon to...

For your eyes only: classify the names of polygons. After providing the definition of a polygon, the video introduces the two major classifications of polygons, concave and convex. The segment of a larger playlist on geometry continues...

What shapes classify as a polygon? The resource provides the definition of a polygon and provides examples of polygons and shapes that are not polygons. The presentation gives an explanation of why each shape falls into the particular...

Extend young mathematicians' understanding of area with a geometry lesson on trapezoids. Building on their prior knowledge of rectangles and triangles, students learn how to calculate the area of trapezoids and other...

Investigate the area and perimeter of polygons in this geometry lesson. Young geometers use grid paper to draw a quadrilateral and calculate its area and perimeter. They also read The Greedy Triangle to identify the changing shape of...

Two-d or not two-d? That's not really the question because the figures here are all two-dimensional. Learners identify the names of polygons, starting with triangles and ending with decagons. The video also describes circles and...

Read any financial website or book, and it is bound to discuss the words asset and liability. But what do these words actually mean to the class? The resource effectively explains by using multiple formats and techniques, including...

Help learners understand the benefits of rearranging a formula. Scholars practice rearranging formulas for specific variables. They also analyze formulas to understand one variable's effect on the other.
