LEARNING OBJECTIVES 

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

1. Explain the meaning of shape construction with wood and metal.

2. Identify materials used for shape construction using wood and metal.

3. Mention methods of constructing shapes with wood and metal.

4. Construct simple shapes using wood and metal (under supervision).

5. State the importance of wood and metal in shape construction.

ENTRY BEHAVIOUR

Pupils have previously learned how to construct shapes using paper and cardboard materials such as squares, rectangles, triangles, and cylinders.

This lesson builds on that knowledge by showing pupils that the same shapes can also be constructed using stronger materials like wood and metal, which are used to make more durable and long-lasting structures in everyday life.

INSTRUCTIONAL MATERIALS

The teacher will teach the lesson with the aid of:

1. Small wooden sticks

2. Nails and hammer (teacher supervised)

3. Metal wires

4. Cardboard for demonstration

5. Glue

6. Pliers

7. Safety materials (gloves if available)

8. Charts showing wooden and metal structures

METHOD OF TEACHING

Choose a suitable and appropriate methods for the lessons.

Note – Irrespective of choosing methods of teaching, always introduce an activities that will arouse pupil’s interest or lead them to the lessons.

CONTENT OF THE LESSON

INTRODUCTION

Shapes are not only made from paper. Strong materials like wood and metal are used to construct stronger and more permanent structures such as chairs, tables, gates, and frames.

LESSON 1 – MEANING OF SHAPE CONSTRUCTION WITH WOOD AND METAL

Shape construction with wood and metal is the process of making different shapes and structures using wooden and metal materials.

Materials Used for Shape Construction

1. Wood Materials

• Wooden sticks

• Planks

• Bamboo

2. Metal Materials

• Iron rods

• Wires

• Nails

• Metal sheets

METHODS OF SHAPE CONSTRUCTION

• Joining

• Cutting

• Bending

• Hammering (for nails in wood)

• Welding (for metal, teacher explanation only)

IMPORTANCE OF WOOD AND METAL IN SHAPE CONSTRUCTION

1. They are strong and durable.

2. They are used for building houses and furniture.

3. They can carry heavy loads.

4. They last longer than paper.

SAFETY PRECAUTIONS

1. Always handle nails and metal carefully.

2. Use tools under teacher supervision.

3. Avoid playing with sharp objects.

4. Wear protective materials if available.

LESSON 2 AND LESSON 3 – SHAPE CONSTRUCTION USING WOOD AND METAL (PRACTICAL ACTIVITIES)

ACTIVITY 1: Making a Simple Wooden Square Frame

Materials:

• Wooden sticks

• Nails or glue

• Hammer (teacher supervised)

Procedure:

• Arrange four wooden sticks to form a square.

• Join the corners using nails or glue.

• Ensure the frame is strong and firm.

ACTIVITY 2: Making a Metal Wire Triangle

Materials:

• Metal wire

• Pliers

Procedure:

• Cut a piece of metal wire.

• Bend it into a triangle shape.

• Join the ends tightly.

Activity 3: Making a Rectangular Wooden Frame

Materials:

• Wooden sticks

• Nails

• Hammer

Procedure:

• Arrange sticks into a rectangle shape.

• Join the corners using nails.

• Check that all sides are firm.

SUMMARY

In this lesson, pupils learned that shape construction can be done using strong materials such as wood and metal.

• Wood and metal are used to make strong and durable shapes and structures.

• Examples of materials include wooden sticks, planks, iron rods, nails, and wires.

• Methods of construction include cutting, joining, bending, and hammering.

• Pupils also learned that shapes such as squares, rectangles, and triangles can be constructed using wood and metal.

• Safety precautions must be observed when handling sharp and heavy materials.

Overall, the lesson helps pupils understand that wood and metal are important materials used in building strong structures in everyday life.
