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 will identify the square and rectangle and know the same and different properties of each shape.
• The pupils will fold a rectangle from a square and investigate the lengths of the sides.

In the process of folding the model, the pupils will investigate the properties of the shapes by composition and decomposition.

• The pupils will study diagonals of polygons.
• The pupils will study lines of reflective symmetry in quadrilaterals and polygons.

Puppy and child.

Pupils will recognize and investigate diagonals formed during the folding process. Pupils will discover which lines of reflective symmetry of a square are also diagonals. Several geometric terms will be revised as well as studying new concepts. There is a following up lesson 2/2 to conclude these concepts.י

Opposite vertices, different types of angles, polygons and quadrilaterals.

Investigating properties of several quadrilaterals.
