Kindergarten Kindergarten: Shapes We compare the 3-D shapes to their 2-D counterparts and talk a lot about the 2-D shapes we see in the 3-D versions. Then we think of examples in real life--and this is where the real fun begins! I challenge the kids to go home and find as many examples of 3-D shapes as they can and bring them into school. We create a Kindergarten Shape Museum!
