Week & Period: Week 33, Period 6
Topic: Geometry – Solid Figures
Sub-topic: 3D Figures and Their Properties
Learning Objectives
By the end of the lesson, students should be able to:
• Categorize geometric figures: cube, cone, cylinder, sphere, prism, pyramid, trapezoid, rhombus
• Identify faces, edges, and vertices of solid figures
• Relate solid figures to real-life objects
Previous Knowledge
Students already know about flat shapes like squares and triangles.
Instructional Materials
Mathematics textbook for Grade 3, cardboard, clay, chart of 3D shapes
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
Teacher shows a ball, a chalk box, and an ice cream cone, then asks: “What shapes do these objects look like?”
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Solid figures are 3D shapes with length, width, and height.
• Cube – 6 square faces, 12 edges, 8 vertices (e.g., dice, boxes)
• Cylinder – 2 circular faces, 1 curved face, no vertex (e.g., tin, pipe)
• Cone – 1 circular face, 1 curved face, 1 vertex (e.g., ice cream cone)
• Sphere – curved surface only, no face, no edge, no vertex (e.g., ball)
• Pyramid – triangular faces meet at a vertex (e.g., Egyptian pyramid)
Example 1: A cube has 6 equal faces, each a square.
Example 2: A cone has 1 flat face and 1 vertex at the tip.
Learners’ Activities (Expanded):
Learners build models using clay and cardboard. Learners count faces, edges, and vertices. They complete a table of properties.
Assessment Checks:
Teacher asks learners:
• How many vertices does a cube have?
• Which shape has no edge?
Notes (Expanded & Detailed):
3D figures are solid objects that we see and use daily. Each figure has unique properties: faces (flat surfaces), edges (lines where faces meet), and vertices (corners where edges meet).
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Teacher summarizes the properties of cube, cone, cylinder, sphere, and pyramid.
Evaluation Method (Expanded):
Exit slip/quiz: Draw and name two 3D shapes you see at home.
Assignment (Expanded):
List 5 real-life objects and identify their solid figure.
Follow-up Activity:
Learners create a chart comparing 3D shapes and their real-world uses.
Differentiation / Inclusive Strategies
Slow learners use physical objects for counting. Fast learners create nets of 3D shapes.
