Term: 3rd Term

Week: 8

Class: Primary 1
Age: 6 years
Duration: 40 minutes (4 periods)
Date:
Subject: Mathematics
Topic: 2-Dimensional Shapes

SPECIFIC OBJECTIVES:

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

  • Identify and name different 2-dimensional shapes (circle, square, rectangle, triangle).
  • Understand the properties of 2D shapes.

INSTRUCTIONAL TECHNIQUES:

  • Explanation, demonstration, and group activities.

INSTRUCTIONAL MATERIALS:

  • Flashcards with 2D shapes, drawing materials.

PERIOD 1 and 2:

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1: INTRODUCTION

- Introduce 2-dimensional shapes using flashcards and real-life examples (e.g., windows, books).

- Pupils listen and discuss examples of 2D shapes in real life.

STEP 2: EXPLANATION

- Explain the properties of 2D shapes (sides, corners). - Introduce the names of basic 2D shapes: circle, square, rectangle, and triangle.

- Pupils listen and observe the teacher’s explanations of 2D shapes.

STEP 3: DEMONSTRATION

- Show examples of each 2D shape and discuss its characteristics (e.g., a square has 4 equal sides).

- Pupils observe and ask questions about the different shapes.

STEP 4: PRACTICE SESSION

- Ask pupils to draw each shape on their own using pencils or crayons.

- Pupils draw the different 2D shapes.

 

EVALUATION:

  1. Name a shape with four equal sides.
  2. How many corners does a triangle have?

CLASSWORK:

  • Pupils draw various 2D shapes on their own, labeling them.

CONCLUSION:

  • Teacher praises pupils for their participation and encourages them to identify shapes at home.

 

PERIOD 3 and 4:

PRESENTATION

TEACHER’S ACTIVITY

PUPIL’S ACTIVITY

STEP 1: INTRODUCTION

- Recap the 2D shapes introduced in the previous lesson.

- Pupils recall and discuss the 2D shapes learned previously.

STEP 2: EXPLANATION

- Explain how to classify 2D shapes based on the number of sides and corners.

- Pupils listen and engage in a discussion about classifying shapes.

STEP 3: DEMONSTRATION

- Show how to classify shapes (e.g., squares, triangles, rectangles) based on their characteristics.

- Pupils observe and ask questions about the classification of shapes.

STEP 4: GROUP ACTIVITY

- Ask pupils to work in pairs to classify shapes from a set of flashcards.

- Pupils work in pairs to classify 2D shapes.

 

EVALUATION:

  1. Classify this shape: A shape with 4 sides but not equal.
  2. How many corners does a square have?

CLASSWORK:

  • Pupils work in pairs to classify various 2D shapes and write down their findings.

CONCLUSION:

Teacher praises pupils for their classification work and encourages them to look for shapes around the classroom.
