The pupils will be able to identify and investigate triangles according to sides and vertices.

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

In this lesson, the pupils will investigate the triangular shapes as formed in the folding process. The classification is made according to the number of sides. At the conclusion of the folding process, the final model comes as a surprise.  The pupils learn new concepts and review previously learnt concepts.

The pupils  will use the measuring tool for comparison of lengths and identification of right angles.

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.
