Date: Week 35
Lesson Duration: 45 minutes
Week & Period: Week 35, Period 6
Topic: Geometry
Sub-topic: Quadrilaterals and Shape Sorting
Learning Objectives
By the end of the lesson, students should be able to:
Define quadrilaterals
Identify examples of quadrilaterals such as squares, rectangles, rhombus, trapezium
Sort shapes into triangles and quadrilaterals
Previous Knowledge
Students already know triangles, rectangles, and circles.
Instructional Materials
Mathematics textbook for Grade 2
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher asks: “Which shape has 3 sides? Which shape has 4 sides?” Teacher introduces the word “quadrilateral.”
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Definition: A quadrilateral is a shape with four sides and four corners (vertices).
Examples:
Square – all sides equal and 4 right angles
Rectangle – opposite sides equal and 4 right angles
Rhombus – all sides equal but no right angles
Trapezium – has one pair of opposite sides parallel
Teacher compares triangles and quadrilaterals.
Teacher shows real-life examples: windows (rectangle), tiles (square), diamond sign (rhombus).
Learners’ Activities (Expanded):
Students cut out paper shapes and sort them into triangles and quadrilaterals
Students create quadrilaterals using straws or sticks
Students go on a shape hunt around the classroom to find quadrilaterals
Assessment Checks:
What is a quadrilateral?
Give two examples of quadrilaterals.
How is a triangle different from a quadrilateral?
Notes (Expanded & Detailed):
Quadrilaterals are four-sided shapes with four corners. Some types of quadrilaterals include squares, rectangles, rhombus, and trapeziums. They are found in everyday life in books, tiles, windows, and signs.
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher revises quadrilaterals and their properties. Students sort shapes into triangles and quadrilaterals.
Evaluation Method (Expanded):
Exit slip/quiz: Draw one square and one trapezium. Write how many sides and corners each has.
Assignment (Expanded):
At home, draw three quadrilaterals and label their names.
Follow-up Activity:
Next lesson will review and compare different types of shapes.
Differentiation / Inclusive Strategies
Teacher uses cut-out shapes for weak learners. Advanced learners classify quadrilaterals further by equal sides or angles.
