Great for K, 1 or 2nd graders. I used this as a review for my 1st graders and they LOVE guessing the answers before they pop up on the screen! This PowerPoint works best as a whole group review, but can be used in small groups to, or put on a student computer for individual use. Students get excited trying to answer questions - how many vertices? What shape is this? Which shape does not belong in this group? Which can NOT roll? Which item is a shape of a triangle? This presentation reviews what 1st graders are tested for concerning 2d and 3d figures, but could also be used as a review for 2nd graders or preview for K.
