key notes:
🔷 What are Sides?
Sides are the straight lines that make up a shape.
Every shape has different number of sides.
Examples:
- Triangle → 3 sides
- Square → 4 sides
- Pentagon → 5 sides
🔶 What are Vertices?
Vertices (corners) are the points where two sides meet.
Each corner of a shape is called a vertex.
Examples:
- Triangle → 3 vertices
- Square → 4 vertices
🔷 Compare Sides and Vertices
Count the number of sides in each shape.
Count the number of vertices (corners).
Compare shapes:
- Which has more sides?
- Which has fewer vertices?
👉 Example:
Triangle vs Square
- Triangle → 3 sides, 3 vertices
- Square → 4 sides, 4 vertices
✔ Square has more sides and vertices
🔶 Important Points to Remember
Number of sides = number of vertices (for basic shapes).
Shapes can be compared by counting.
Use words like:
- More / Less
- Equal
- Same / Different
🎯 Simple Activity for Students
Draw a triangle, square, and rectangle.
Count sides and vertices for each.
Ask:
- Which shape has the most sides?
- Which has the least vertices?
learn with an example
Which shape has fewer vertices?
solution:
Next, count the vertices all around this shape.
5 is less than 6.
So, this shape has fewer vertices.
Which shape has fewer sides?
solution:
Count the sides of both shapes.
First, count the sides all around this shape.
Next, count the sides all around this shape.
3 is less than 6.
So, this shape has fewer sides.
let’s practice:
