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.

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

Pupils will recognise perpendicular lines and draw perpendicular lines.

In this lesson the pupils will investigate perpendicular and intersecting lines. At the conclusion of this lesson the final model will be a surprise while learning new concepts and revising previously learnt geometrical concepts.

Angles,right angle,sides of a polygon.

• 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.

התלמידים יחקרו את התכונות של הריבוע, המלבן, הדלתון, המעוין והטרפז.

התלמידים יחקרו את המרובעים: ניתוח תכונות, מיון מרובעים, קביעת קשרי הכלה.
