Week Lesson Strand Sub-strand Lesson Learning Outcomes Learning Experiences Key Inquiry Question(s) Learning Resources Assessment Reflection
2 1 Measurements and Geometry 2.3 Trigonometry By the end of the lesson, the learner should be able to:
a) make a simple clinometer using locally available materials;
b> construct from cardboard;
c> appreciate hands-on learning.
The learners will be guided to:
i> Project: Make clinometer;
ii> use straw, protractor, string;
iii> calibrate (Core competency: Learning to learn; PCI: Self-esteem).
How can we measure angles with local materials? Straws, protractors, string Clinometer project assessed using a learning to learn and self-esteem rubric
2 2 Measurements and Geometry 2.3 Trigonometry By the end of the lesson, the learner should be able to:
a) use the clinometer as a learning resource;
b> measure real angles;
c> appreciate practical trigonometry.
The learners will be guided to:
i> use clinometer in field;
ii> calculate heights;
iii> document (Core competency: Learning to learn; PCI: Self-esteem).
How accurate is our clinometer? Clinometers, portfolios Field task assessed using a learning to learn and self-esteem rubric
2 3 Measurements and Geometry 2.4 Area of Polygons By the end of the lesson, the learner should be able to:
a) compute area of a triangle given two sides and an included acute angle;
b> use real objects;
c> appreciate trigonometric area.
The learners will be guided to:
i> identify triangular objects (mats, tiles);
ii> measure sides/angle;
iii> calculate area (Core competency: Creativity; PCI: Social Awareness Skills).
What is the area of this triangular mat? Mats, tiles, protractors Area calculation assessed using a creativity and social awareness rubric
2 4 Measurements and Geometry 2.4 Area of Polygons By the end of the lesson, the learner should be able to:
a) determine the area of a triangle given three sides using Heron's Formula;
b> use tripod stands;
c> appreciate alternative methods.
The learners will be guided to:
i> identify triangular shapes (tripod stands);
ii> measure sides;
iii> work out area (Core competency: Learning to learn; PCI: Social Awareness Skills).
How do we find area when we only know sides? Tripod stands, rulers Heron's task assessed using a learning to learn and social awareness rubric
2 5 Measurements and Geometry 2.4 Area of Polygons By the end of the lesson, the learner should be able to:
a) determine the area of a rhombus and parallelogram in different situations;
b> use floor patterns;
c> appreciate real-world area.
The learners will be guided to:
i> identify rhombus/parallelogram patterns;
ii> measure sides/angle;
iii> calculate area (Core competency: Creativity; PCI: Social Awareness Skills).
What is the area of this floor pattern? Floor patterns, fabrics Area task assessed using a creativity and social awareness rubric
