#### Perpendicular and parallel straight lines 1 1/2

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

• Name of Model
• There is no model in this lesson.

• The Lesson Structure
• According to planned curriculum.

• Lesson content
• 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.

#### Perpendicular and parallel straight lines 2 2/2

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

• Name of Model
• A dress.

• The Lesson Structure
• According to the curriculum.

• Lesson content
• 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.

• Prior Knowledge
• The concepts of angle,straight angle and square.

#### Unit of measurement for measuring Volume-a cube.

• Lesson Aims
• Recognizing the concept of volume.
• Recognizing the use of an accepted unit of volume measurement-a cube.
• Recognizing which measurements are necessary for determining the volume of a prism.
• Recognizing that different structures may have the same volume but different heights.
• The Name of the Model
• Structures built with cubes.

• Lesson Content
• The pupils will construct two different sized cubes by a folding process. Using these cubes the pupils will measure the volume of a container and reach the understanding that a number representing a volume measurement must relate to the unit of measurement used. Pupils will learn that different structures assembled with the same number of cubes may have different heights.Height measurement alone is insufficient for volume measurement.

• Materials
• Origami sheets of 2 sizes. 10 x 10 cm,15 x 15 cm.
