This site provides students with a variety of different geometry activities to choose from. Some activities, such as "Area of Polygons" and "Types of Triangles," begin with an animated video that will help students learn about terms such as polygons, vertices and segments and identify different geometric shapes. The educational videos are followed by games and quizzes to help reinforce the material.
Students will be able to test their knowledge of geometric shapes while challenging their brains in this hidden picture puzzle. After printing the triangle grid paper, students must locate 12 different polygons on the page and shade in their answers. Definitions of each polygon, such as isosceles trapezoid and parallelogram, can be found on the site.
Using colored paper, a pair of scissors and a ruler, students can create their own set of tangrams in this activity. Students will create seven different shapes to complete their set of tangrams, which can be used to practice creating different geometric shapes or in other geometry activities. Detailed steps and corresponding illustrations are provided on the site.
Utah State University's National Library of Virtual Manipulatives provides an extensive list of browser-based virtual playgrounds that allow students to learn about geometrical shapes and patterns. Activities are separated by grade level and include things like geoboards to help students understand area and perimeter, building different types of triangles, solving problems using tangrams and discovering patterns using shapes.
This compilation of geometry activities was created by a workshop and intended as a source of information for math teachers. The activities range across all levels of difficulty and include items such as Nature's Pentagrams, where students examine common items such as flowers and apples to discover geometric shapes and patterns, and Tessellation Activity, where students learn about polygons through the concept of tiling, or using the same shape to cover a surface area.
