Term: 3rd Term

Week 3

Class: Primary 5
Age: 10 years
Duration: 40 minutes × 5 periods
Date:
Subject: Mathematics
Topic: Plane Shapes

SPECIFIC OBJECTIVES:

By the end of the lesson, pupils should be able to:

  1. Identify types of quadrilaterals (rhombus, square, rectangle).
  2. State the basic properties of rhombus, square, and rectangle.
  3. Recognize quadrilaterals and list their properties.
  4. Use real objects to discuss parts of a circle (radius, diameter, center, chord).
  5. Draw a circle with a specific radius using a compass.
  6. Solve quantitative reasoning problems involving properties of plane shapes.

INSTRUCTIONAL TECHNIQUES:

  • Demonstration
  • Group discussion
  • Inquiry-based learning
  • Problem-solving activities
  • Use of real-life objects

 

INSTRUCTIONAL MATERIALS:

  • Cardboard cutouts of shapes (square, rectangle, rhombus, etc.)
  • Compass, ruler, pencils
  • Chart showing different quadrilaterals and circles
  • Real-life objects (bottle tops, lids, books, boxes)
  • Worksheets for exercises
  • Flashcards with properties of shapes

 

INSTRUCTIONAL PROCEDURES:

PERIODS 1 & 2

PRESENTATION

Step

Teacher’s Activity

Pupils’ Activity

STEP 1 – INTRODUCTION

Introduces plane shapes using real objects (e.g., books, tiles, etc.) to show square, rectangle, rhombus.

Pupils observe and identify shapes in real objects.

STEP 2 – EXPLANATION

Displays and describes the features of a square, rectangle, and rhombus using charts and flashcards.

Pupils listen and compare the properties of the shapes.

STEP 3 - DEMONSTRATION

Demonstrates identifying sides, angles, and parallel lines in shapes. Uses flashcards to quiz pupils on shape recognition.

Pupils describe properties such as equal sides and right angles.

STEP 4 - NOTE TAKING

Pupils copy notes on properties of square, rectangle, and rhombus.

Pupils write notes in their notebooks.

NOTE (On the Board):

  • Square: 4 equal sides, 4 right angles, opposite sides are equal and parallel.
  • Rectangle: Opposite sides equal and parallel, 4 right angles.
  • Rhombus: 4 equal sides, opposite angles equal, opposite sides parallel.

EVALUATION:

  • Pupils identify a shape and state its properties.
  • Differentiate between square and rhombus.

CLASSWORK:

  • Fill a table comparing square, rectangle, and rhombus.

ASSIGNMENT:

  • Find and draw 3 real-life objects that represent square, rectangle, or rhombus.

CONCLUSION:
The teacher commends pupils for active participation and reminds them to look around their homes for shapes.

 

PERIODS 3 & 4

PRESENTATION

Step

Teacher’s Activity

Pupils’ Activity

STEP 1 – INTRODUCTION

Recaps the previous lesson. Asks pupils to name 4-sided shapes (quadrilaterals).

Pupils mention names of quadrilaterals.

STEP 2 – EXPLANATION

Explains what quadrilaterals are and their basic features.

Pupils take notes and observe displayed shapes.

STEP 3 - DEMONSTRATION

Uses flashcards to show examples of quadrilaterals. Discusses sides, angles, and symmetry.

Pupils handle cutouts and describe features.

STEP 4 - NOTE TAKING

Pupils write the properties of quadrilaterals.

Pupils copy notes from the board.

NOTE (On the Board):

  • Quadrilaterals have 4 sides.
  • Types: square, rectangle, rhombus, trapezium, kite.
  • All quadrilaterals have 4 angles.

EVALUATION:

  • Name any 3 quadrilaterals and state two properties each.

CLASSWORK:

  • Match given shapes to their properties.

ASSIGNMENT:

  • Draw and label any 3 types of quadrilaterals and write 1 real-life object that matches each.

CONCLUSION:
The teacher summarizes the lesson and encourages pupils to identify quadrilaterals at home.

 

PERIOD 5

PRESENTATION

Step

Teacher’s Activity

Pupils’ Activity

STEP 1 - INTRODUCTION

Shows circular objects and asks pupils to name them.

Pupils name familiar circular items (plates, coins).

STEP 2 - EXPLANATION

Explains the components of a circle (center, radius, diameter, chord).

Pupils listen and take notes.

STEP 3 - DEMONSTRATION

Uses a compass to draw a circle and labels its parts.

Pupils practice drawing circles using compass.

STEP 4 - NOTE TAKING

Pupils write down definitions and draw labelled diagrams.

Pupils draw and label: radius, diameter, chord.

NOTE (On the Board):

  • Radius: Distance from center to any point on the circle.
  • Diameter: Distance across the circle, passing through center (2 × radius).
  • Chord: A line connecting two points on the circle.
  • Example: Draw a circle of radius 4 cm. Label its radius and diameter.

EVALUATION:

  • Pupils identify and label parts of a circle from a diagram.
  • Solve simple word problems involving radius and diameter.

CLASSWORK:

  • Draw circles of different radii and label their parts.

ASSIGNMENT:

  • Find 3 circular objects at home and measure their diameters (using ruler or tape).

CONCLUSION:
The teacher appreciates the pupils’ efforts and reminds them to keep practicing drawing and measuring shapes.

SUMMARY OF THE LESSON:

This week, pupils learned how to identify and describe various plane shapes, including square, rectangle, rhombus, and other quadrilaterals. They explored their properties and real-life examples. Pupils also learned about circles, their components, and how to draw them using a compass. The week ended with practical activities and problem-solving exercises related to plane shapes.
