Constructing a cuboid.

Cuboid.

According to the syllabus.

In this activity pupils learn how to construct a cuboid according to given dimensions.

Quadrilaterals, polygons, prisms and cuboids.

6 square grid sheets, two of each color.

• 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.

Structures built with cubes.

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.

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

• Classifying triangles according to the angles of the triangles.
• Identifying right angled triangles, acute triangles and obtuse triangles.
• Classifying triangles according to the sides of the triangles.
• Drawing and naming triangles according to both properties of sides and angles.

The angled bird.

In this lesson pupilsinvestigate different triangles formed as a result of folding the model. A surprise final model using old and new terms for descriptions.

The concept of a right angle and visual representation of an angle.
