SMASE – ASEI PDSI METHOD

THIRD TERM

WEEK 8

PRIMARY 2

TOPIC: Two Dimensional Shapes

LEARNING AREA

• Lesson One – Two Dimensional Shapes I
• Lesson Two – Two Dimensional Shapes II
• Lesson Three – Square Corners in Two Dimensional Shapes
• Lesson Four – Corners in Other Two Dimensional Shapes
• 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 a square, a rectangle, a circle and a triangle.
2. indicate which corner of a two dimensional shape is a square corner.

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 cubes, match boxes, tins, paper cuttings and drawings of squares, rectangles, triangles, circles.
