Shapes

✨ Section 1: What Are Shapes?

A shape is a form or figure that we can see and describe.
We see shapes everywhere — in toys, signs, food, and buildings!

In Grade 1, we learn to recognize two kinds of shapes:

• 🟢 2D Shapes — flat shapes
  
  

• 🔷 3D Shapes — solid shapes
  
  

🔲 Section 2: What Are 2D Shapes?

2D shapes are flat. You can draw them on paper. They only have:

• Length and width
  
  

• No thickness
  
  

🧠 Common 2D Shapes:

Sides

Example Item

Circle

Clock, coin

Triangle

Pizza slice, sign

Square

4

Window, checkerboard

Rectangle

Door, book

Pentagon

5

House top, badge

Hexagon

6

Honeycomb

✅ Tip: We describe 2D shapes by counting their sides and corners.

🎲 Section 3: What Are 3D Shapes?

3D shapes are solid. You can pick them up, roll them, and stack them.

They have:

• Length, width, and height
  
  

• Some have flat faces, some have curved surfaces

🔍 Section 6: Describe and Sort Shapes

Can you match the shape to its object?

• Circle → ___ (Pizza, coin)
  
  

• Cone → ___ (Party hat, ice cream)
  
  

• Cube → ___ (Gift box, dice)
  
  

• Rectangle → ___ (Book, door)
  
  

📌 Encourage students to look around their home or classroom for real shapes!

📘 Section 7: Key Words to Learn

• Side – a straight edge of a 2D shape
  
  

• Corner – where two sides meet (also called a vertex)
  
  

• Face – the flat surface on a 3D shape
  
  

• Edge – where two faces meet
  
  

• Solid – another word for 3D shape
