Triangles activity A,  Triangles activity B , Polygon activity A, Polygon activity A, Polygon activities B 1/2 ,  Polygon activities B 2/2 , Polygon activity C , A measuring tool for comparison of lengths , Quadrilaterals A , Quadrilaterals B: Square & Rectangle – same and different, Quadrilaterals C: Square & Rectangle Line of reflective symmetry 1/2, Line of reflective symmetry 2/2,  , Lines of symmetry in quadrilaterals, Translation of shapes

Pupils will identify right angles intuitively using the measuring tool.

Pupils will identify right angles in various orientations.

The measuring tool should be folded  and kept in the pupils workbook at the conclusion of each lesson.

Intuitive  identification  of right angles.

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.

Polygon activity 3 decomposition and composition 1/2

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.

      .Concepts of sides and vertices in polygon, Parallels side

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.

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.

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.

Polygons

This activity demonstrates the different stages of folding and investigating the polygons formed with the folding.
