In this shapes picture quiz worksheet, students complete a set of 12 multiple choice questions, identifying shapes. A reference web site is given for additional activities.

Young scholars identify interior and exterior angles of polygons. For this geometry lesson, students add interior and exterior angles of polygons. They use angle theorems to solve the problems.

Students calculate the sum of the angles of a polygon. In this geometry lesson plan, students use the interior angle formula of polygon based on the number of sides of the polygon. They identify the missing angle using algebra.

Sixth graders investigate tessellations and their origins. Students trace triangles to form a tessellation. They measure the angle of equilateral triangles. Students locate the line of symmetry, they create geometric squares,...

Middle schoolers work together to create mobiles with different polygons. They research the polygon and list its characteristics. They may present to the class if they chose to.
