Content:

Understanding Scale in Model Making:
- Scale 1:20 means that 1 unit on the model represents 20 units in real life. For example, if the real room is 5 meters long, it will be 25 cm on the model.
- Explain how to use this scale to measure and cut materials for the model.
Designing the Two-Bedroom Flat:
- Provide students with a floor plan of a two-bedroom flat, and guide them to understand the layout, including walls, windows, doors, and other important features.
- Discuss how to measure each component of the floor plan and adjust it to fit the scale of 1:20.
Materials and Tools:
- Introduce the materials (cardboard, scissors, glue, etc.) and demonstrate how to use them to construct walls, windows, doors, and the roof of the model.
- Show how to cut and assemble pieces precisely to scale.
Building the Model:
- Guide students to first cut out the walls, floors, and roof of the building using cardboard.
- Instruct them to carefully glue the walls and roof together, following the floor plan.
- Show how to add windows, doors, and other features using smaller pieces of cardboard or markers to represent details.

Presentation Steps:

Introduction to the Project:
- Explain the objectives and steps involved in creating a model of the two-bedroom flat.
Understanding the Scale:
- Demonstrate how to convert the floor plan into a scaled-down model, measuring each room and feature according to the 1:20 scale.
Material Selection:
- Introduce the materials, tools, and safety precautions.
- Demonstrate how to measure, cut, and assemble the materials to create the structure.
Model Construction:
- Guide students through the process of creating their models, providing support and ensuring accuracy in measurements and cutting.
Final Touches:
- Assist students in adding final details to their models, such as doors, windows, and roof. Discuss how to present the completed project.

Teacher’s Activities:

Provide students with the floor plan of the two-bedroom flat and explain how to convert the measurements to scale.
Demonstrate the use of materials and tools for cutting, measuring, and assembling the model.
Walk around to assist students as they work, offering tips and ensuring that they follow the scale accurately.

Learners’ Activities:

Study the floor plan and identify the key components to scale.
Use rulers, scissors, and glue to create the walls, doors, and roof of the model.
Collaborate with classmates and share ideas for improving the quality of the model.
Present their completed models to the class.
