Shapes All Around Us
A friendly early-years geometry lesson: learn circles, squares, triangles and rectangles, count their sides, and spot shapes in real life.
Key takeaways
- A circle is round with no corners
- A triangle has 3 sides and 3 corners
- A square has 4 equal sides; a rectangle has 4 sides too
- Shapes are everywhere around us
Shapes are everywhere
Look around you. Shapes are hiding in lots of places! Let's meet four friendly shapes.
The circle
A circle is round. It has no corners and no straight sides.
⚪ Think of a ball, the sun, or a wheel.
Trace a circle in the air with your finger. Round and round!
The triangle
A triangle has 3 sides and 3 corners.
🔺 Think of a slice of pizza or a party hat.
Tri means three. So a triangle always has three sides!
The square
A square has 4 sides. All four sides are the same length.
🟦 Think of a window or a cracker.
The rectangle
A rectangle also has 4 sides. But two sides are long and two sides are short.
▬ Think of a door, a book, or a phone.
Count the sides
Here is a little table to help you remember.
| Shape | Sides | Corners |
|---|---|---|
| Circle | 0 | 0 |
| Triangle | 3 | 3 |
| Square | 4 | 4 |
| Rectangle | 4 | 4 |
Shape hunt!
Now it is your turn. Go on a shape hunt around your home.
- Can you find a circle? Maybe a clock!
- Can you find a triangle? Maybe a roof!
- Can you find a square or rectangle? Maybe a TV!
Well done!
You know four shapes now. Great work!
