Lesson notes

Learning Objectives

Indicator: 2.3.2.LI.4 - Discuss roofs.

By the end of the lesson, learners can:

Explain the roof as a superstructure component that protects the building from weather and provides stability.
Outline at least four common types of roofs, including flat, gable, hip, and skillion or shed roofs.
Describe the functions of a roof, including weather protection, thermal insulation, and load transfer to walls.
Identify and list at least five common roofing materials used in Ghana and state one advantage of each.
Differentiate between the structural frame (roof members) and the roof covering, and explain how they work together.

Curriculum details

Strand: Building Construction Technology (Strand 3)
Sub-strand: Substructure and Superstructure (3.2)
Content standard: 2.3.2.CS.2 - 2.3.2.CS.2 Demonstrate knowledge and understanding of Load bearing and non-Load bearing components of the superstructure. 2.3.2.LO.1 Categorize and describe foundations used under various soil conditions. 2.3.2.LO.1 Be able to differentiate Load bearing from non-load bearing components and their functions in the Super structure.
Indicator: 2.3.2.LI.4 - Discuss roofs.
Suggested placement: Semester 1, Week 19 (Week 19 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

Communication: In a whole class ask learners to explain roofs as building components of the Superstructure.
Collaboration:
- In mixed-ability groups ask learners to outline types of roof.
- This method is to enhance effective participation in teaching and learning by different learners including the Approaching Proficiency, Proficiency and Highly Proficient.
- (Identification of ability of learners and positioning to ensure mixed ability).
- In structured groups (GESI) ask learners to discuss the functions of the roof as a component of the Superstructure.
- In mixed-ability groups ask learners to outline materials used in roofing.

Assessment (2.3.2.AS.4). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.

Teaching and Learning Materials:
- Use of Simulation; Virtual to illustrate setting out.
- Use of Flip Chat to illustrate excavations.
- Use of Simulation, Virtual and Typical foundational works as seen in progress at different Construction sites to discuss various types of foundations given the soil type.
- The use of Simulation; (virtual) to illustrate types of load-bearing and non-load bearing members of the superstructure.
- The use of Superstructure works as observed at different Construction sites to illustrate the use of load and non-load bearing members.
- The use of flip-charts to illustrate types and functions of load-bearing and non- load bearing members of the Superstructure.
