What are 2-d and 3-d shapes?
If you can make it just by cutting it out of a piece of paper, it's 2-d. If you can make it by carving a block of wood, it's 3-d. 2-d shapes have length and width, but not height. 3-d shapes have length, width, and height. Here's an example: a rectangle might be 2" long and 5" wide, but those are the only numbers you use, so it's a 2-d shape. A house is 60' long, 25' wide, and 10' tall, so it's 3-d.
