#### Polygon activities B 1/2

• Lesson Aims
• The pupils during the folding process will identify polygons according to stated properties. The pupils will learn how to form different polygons with their sheets and investigate the various properties of the folded shapes.

• Model Name
• Polygon activities 1/2

• Lesson content
• The decomposing and composing activities allow the children to create various polygons during the folding process and with the combination of several triangular folded shapes. With a series of questions and answers during the folding process the pupils are able to deepen their geometric reasoning in a dynamic environment.

• Prior knowledge
• Concepts of sides and vertices in polygons.

#### Polygon activity 3 decomposition and composition 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

• The lesson structure
• 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.
