MATHEMATICS

SMASE – ASEI PDSI METHOD

THIRD TERM

WEEK 2

PRIMARY 5

TOPIC: Plain Shapes – Parallel and Perpendicular Lines

LEARNING AREA

Lesson One – Parallel and Perpendicular Lines

Lesson Two – Triangles and Properties of Triangle

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 parallel and perpendicular lines.

2. state some properties of triangles.

3. state some properties of quadrilateral.

4. solve some quantitative aptitude problems.

RATIONALE

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.

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

LEARNING MATERIALS

The teacher will teach the lesson with the aid of:

2 and 3 dimensional shapes.

Models of: equilateral, isosceles, right angled triangles, square and rectangle.

PREVIOUS KNOWLEDGE

Plane 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.

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