# Three (3) Dimensional Shapes – Cubes, Cuboids and Prisms (Primary 5)

MATHEMATICS

SMASE – ASEI PDSI METHOD

THIRD TERM

WEEK 5

PRIMARY 5

TOPIC: 3 Dimensional Shapes – Cube, Cuboid and Prisms

LEARNING AREA

Lesson One – Introduction to 3 dimensional shapes

Lesson Two – Nets of Cubes and Cuboids

Lesson Three – Net of triangular and square Pyramid

Lesson Four – Nets of Square base and triangular prism

Lesson Five – Revision, Quantitative and Test

TIME – 40 Minutes each.

LEARNING OUTCOME

By the end of the lesson, pupils should be able to:

1. identify prisms and pyramids.

2. state properties of 3 dimensional shapes such as cubes, cuboids, pyramids, etc.

3. draw nets of 3-D shapes.

4. construct cube, Cuboid, and prisms.

5. Quantitative reasoning related to 3-dimensional shapes.

RATIONALE

The objects around you — the ones you can pick up, touch, and move around — are 3 dimensional. These shapes have a third dimension: depth. Cubes, prisms, pyramids, spheres, cones, and cylinders are all examples of 3 dimensional objects. The 3 dimensional objects can be rotated in space.

The concept of 3 dimensional shapes will enable pupils to understand and appreciate their relevance in our daily life.

LEARNING MATERIALS

The teacher will teach the lesson with the aid of:

Graph paper

Cardboard sheets

Models of 3 dimensional shapes, etc.

PREVIOUS KNOWLEDGE

A cube, rectangular prism, sphere, cone and cylinder are the basic 3-dimensional shapes we can see around us. The concept of 3 dimensional shapes will expose to discover various 3 dimensional shapes.
