MATHEMATICS

SMASE – ASEI PDSI METHOD

THIRD TERM

WEEK 6

PRIMARY 6

TOPIC: Plane and Solid Shapes – Triangle, Square, Rectangle, Cube and Cuboid

LEARNING AREA

• Lesson One – Properties of Triangle
• Lesson Two – Properties of Square and Rectangle
• Lesson Three – Properties of Cube and Cuboid
• Lesson Four – Quantitative Reasoning
• Lesson Five – Revision and Test

TIME – 40 Minutes each.

LEARNING OUTCOME

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

1. identify and state properties of triangles.
2. identify and state  properties of quadrilateral.
3. identify and state the Properties of cube and cuboid.
4. solve some quantitative aptitude problems.

RATIONALE

Shapes are plane and solid shapes. Plane shapes in mathematics are any closed, flat, 2-dimensional shapes. They include triangle, quadrilateral and polygon. Plane shapes are made of straight lines, curved lines, or both straight and curved lines.

Many objects that you see in your day to day life like book, pencil box, ice cream cone, football and cylinder are 3-dimensional objects. All these objects occupy some shape and have three dimensions – length, breadth and height or depth.

In this lesson, the pupils will learn what plane and solid shapes are and explore their different types and properties.

LEARNING MATERIALS

The teacher will teach the lesson with the aid of:

1. 2 and 3 dimensional shapes.
2. Models of: equilateral, isosceles, right angled triangles, square, rectangle, cube and cuboid.

PREVIOUS KNOWLEDGE

Plane and Solid shapes are all around us. These stop signs (all traffic signs are plane shapes), a sheet of paper, a paper plate, a stamp, etc. There are many kinds of plane Shapes. Book, pencil box, ice cream cone, football and cylinder are 3-dimensional objects.

In this lesson, we will focus on the following – triangles squares, rectangles, cube and cuboid.
