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 following quadrilaterals: Square,rectangle,trapezoid.

Space ship.

In this lesson the pupils will investigate through folding different quadrilaterals and their properties. The final shape will be a surprize for the pupils.While folding the pupils will learn new concepts and revise previously learnt concepts.

The concepts of vertices and  sides of polygons.

• Recognition of quadrilaterals especially kite,rhombus and square.
• Recognition of the properties of diagonals in a square and rhombus.

The pecking bird.

The folding process enables the pupils to investigate quadrilaterals and recognize the special properties of each polygon. There is a revision of previously learnt concepts and an introduction to new concepts. The final model becomes as a surprise to the pupils.

Cocepts of quadrilaterals, sides and vertices.

• Origami sheets 15 x 15 cm.

• 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.

The concepts of vertex, side and polygon

• The pupils will identify the following quadrilaterals: a square,a rectangle and will compare the same and different properties of each quadrilateral.
• The pupils will fold various rectangles and squares comparing lengths of sides.

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

During the folding processes the pupil will relate to perpendicular and parallel lines and segments.

There is no model in this lesson.

According to planned curriculum.

This is a prepatory lesson to the next lesson about parallel and perpendicular lines and segments with the model of a dress. In the lesson the pupils investigate the properties of parallel and perfpendicular lines using  their measuring tool.

The concepts of angle,a right angle and a square.

• The study of Perpendicular Lines and Perpendicular Sides of Polygons.
• Comparison of angle sizes.
• Investigation of angles and  Perpendicular Lines and Perpendicular Sides of Polygons.

The measuring tool,Composition and Decomposition,Polygons 3,Perpendicular Lines and Perpendicular Sides of Polygons.

In this lesson the pupils will investigate intersection of straight lines,perpendicular lines and perpendiculars sides of Polygons. The model comes as surprise while learning new concepts and revising previously learnt concept.

.The concepts of Angle, Right Angle,Square and Pentagon

Measuring Tool, origami sheets 15×15 cm.

Pupils will recognise perpendicular lines and draw perpendicular lines.

The measuring tool,Composition and Decomposition of Shapes, Polygons 3,Perpendicular  lines and sides of polygons.

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.

During the folding process the pupils will identify parallel and perpendicular lines.

A dress.

According to the curriculum.

This is the second lesson on parallel and perpendicular lines following the prepatory lesson on parallel and perpendicular lines-1 1/2. In this lesson will identify aparallel and perpendicular lines in other situations. The final model will be  a surprise for the pupils and at the same time learning new concepts and revising previously learnt concepts.

The concepts of angle,straight angle and square.

• התלמידים ישתמשו במושג אלכסון. התלמידים יבנו ויזהו אלכסונים במצולע.
• התלמידים יחקרו תכונות של מרובעים על פי תכונות הסימטריה.

מומלץ ללמד לפי הרצף המופיע באתר (הרצף על פי תכנית הלימודים). ​

התלמידים יזהו ויבחנו את האלכסונים שיופיעו במהלך הקיפול. התלמידים יבחינו בין אלכסונים שהם גם קווי סימטריה לבין אלכסונים שאינם קווי הסימטריה  במרובעים. בסיום השיעור מתקבל התוצר הסופי כהפתעה, תוך לימוד מושגים חדשים וחזרה על המושגים שנלמדו בשיעורי ההכנה. לאחר שיעור זה מומלץ ללמד את שיעור הסיכום.
