Lesson notes

Learning Objectives

Indicator: 1.2.2.LI.1 - Explain types of solid geometrical figures and give examples.

By the end of the lesson, learners can:

Define solid geometry and distinguish it from plane geometry, giving at least one characteristic of each.
Identify and name at least six types of solid geometrical figures (prisms, pyramids, cylinders, cones, spheres, and composite solids).
Classify given solids into their correct families (for example, sorting a triangular prism as a prism) and justify their reasoning.
Give at least two real-life examples of each major type of solid from their environment, including objects found in Ghanaian homes, markets, and workplaces.
Sketch a labelled diagram of each major solid type, showing its faces, edges, and vertices where applicable.

Strand: Geometry (Strand 2)
Sub-strand: Solid Geometry (2.2)
Content standard: 1.2.2.CS.1 - 1.2.2.CS.1 Apply the concept of solid geometry in designing. 1.2.2.LO.1 Use the understanding of solid geometry to draw three-dimensional objects in isometric, oblique, perspective and design artefact base on solid geometrical figures
Indicator: 1.2.2.LI.1 - Explain types of solid geometrical figures and give examples.
Suggested placement: Semester 2, Week 10 (Week 30 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)

Talk for Learning: With the use of pictures, engage learners to review their knowledge on solid geometry at the basic level and based on this, assist learners to explain solid geometry.

Assessment (1.2.2.AS.1). The document marks these depth-of-knowledge levels for this indicator: Level 2 Skills of conceptual understanding; Level 3 Strategic reasoning.
