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 activities 1/2

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, Line of reflective symmetry 1/2, Line of reflective symmetry 2/2, Quadrilaterals C: Square & Rectangle , Lines of symmetry in quadrilaterals, Translation of shapes

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 polygons.

The pupil will identify the properties of the translation transformation.

A car

First Stage: A prepatory lesson on the topic of the reflective transformation, reflection and line symmetry,the line of symmetry in quadrilaterals, and rotational symmetry.

Second stage: The measuring tool,a prepatory lesson on the topic of the reflective transformation, reflection and line symmetry, opposite and adjacent vertices,the diagonal as a line of symmetry in quadrilaterals,rotational symmetry and translation of shapes.

Translation as one of three transformations-Reflection,Translation,Rotation as studied in elementary school. In this lesson pupils will fold the model of a car and investigate the properties of translation, congruency of shape, the same distance in each translation of the shape and the same direction for each translation of the shape.
