2-D and 3-D shapes

In first grade, we have to teach the 2-D shapes of circle, triangle, rectangle, trapezoid, and rhombus.  For 3-D shapes we teach cylinder, sphere, pyramid, and rectangular prism.  To introduce these shapes, I created the following powerpoints.  They name the shape and also count the sides, edges, vertices, and faces.  My students really enjoy participating with the presentations.
