What makes 3D shapes different from 2D shapes?
- 3D shapes have depth, width, and height, while 2D shapes only have width and height.
- Think of 3D shapes as objects you can hold, like a ball or a box.
- 2D shapes are flat and you can't pick them up, like a drawing in a book.
Examples:
- A cube vs. a square:
- A cube is a 3D shape, like a dice, and has 6 flat squares as its sides.
- A square is a 2D shape, flat like a piece of paper.
- A sphere vs. a circle:
- A sphere is a 3D shape, like a basketball, and is round on all sides.
- A circle is a 2D shape, like a ring, and is flat.
- A cylinder vs. a rectangle:
- A cylinder is a 3D shape, like a can of soda, and has circular ends.
- A rectangle is a 2D shape, like a door, and is flat.
