This is an instructional task that gives students a chance to reason about lines of symmetry and discover that a circle has an an infinite number of lines of symmetry. Even though the concept of an infinite number of lines is fairly abstract, fourth graders can understand infinity in an informal way.

This task provides students a chance to experiment with reflections of the plane and their impact on specific types of quadrilaterals. It is both interesting and important that these types of quadrilaterals can be distinguished by their lines of symmetry.

In this task, students will apply their knowledge of polygons and their properties to create “New-Fangled Tangram” puzzles.  Students will need to pull from their understanding that polygons may have shared attributes, utilize visual-spatial skills, and employ a variety of problem solving strategies. Additionally, students will need to prove that their puzzles were designed correctly by using a variety of tools and apply fourth grade knowledge of polygons.  This lesson was developed by NCDPI as part of the Academically and/or Intellectually Gifted Instructional Resources Project. This lesson plan has been vetted at the state level for standards alignment, AIG focus, and content accuracy.
