Polygon activity  decomposition and composition B 2/2

Polygon activity decomposition and composition B 2/2

  • Lesson Aims
  • The pupils will fold and identify shapes according to their properties.

    The pupils will use paper folding in order to make geometric shapes and investigate their properties.

  • Name of Model
  • A rabbit finger puppet

  • Lesson content
  • In this lesson the pupils investigate polygons that are formed during the folding process. There is a surprise at the end of the lesson.  The pupils learn new concepts and refresh their previous learning.

  • Prior knowledge
  • If during the folding process there are cases of inexact folding by some of the pupils, then these cases will be used to identify differences between the polygons and their properties. The pupils will also learn the concept of polygon sides and vertices.
