2-D and 3-D Shapes

For Grade 3 students, learning about 2D and 3D shapes is an exciting introduction to geometry. At this level, the focus is on recognizing shapes, understanding their properties, and differentiating between 2D (flat) and 3D (solid) shapes.

The following diagram shows some 2-dimensional shapes. Scroll down the page for more examples of 2-dimensional shapes.

2D Shapes (Two-Dimensional Shapes)
2D shapes are flat shapes that have only length and width. They lie on a plane and have area but no volume. They are flat and can be drawn on a piece of paper.

Common 2D Shapes

1. Circle:
   A round shape with no sides or corners.
   
2. Triangle:
   A shape with 3 sides and 3 corners.
   
3. Square:
   A shape with 4 equal sides and 4 right angles.
   
4. Rectangle:
   A shape with 4 sides (opposite sides are equal) and 4 right angles.
   
5. Pentagon:
   A shape with 5 sides and 5 corners.
   
6. Hexagon:
   A shape with 6 sides and 6 corners.
   

3D Shapes (Three-Dimensional Shapes)
3D shapes are solid shapes that have length, width, and height. They occupy space and have volume.

Common 3D Shapes

1. Cube:
   A box-shaped object with 6 square faces, 12 edges, and 8 corners.
   
2. Cuboid (Rectangular Prism):
   A box-shaped object with 6 rectangular faces, 12 edges, and 8 corners.
   
3. Sphere:
   A perfectly round shape with no edges or corners.
   
4. Cylinder:
   A shape with 2 circular bases and 1 curved surface.
   
5. Cone:
   A shape with 1 circular base, 1 curved surface, and 1 pointed tip.
   
6. Pyramid:
   A shape with a base (e.g., square or triangle) and triangular faces that meet at a point.
