Use blocks to show your children that two shapes put together make a completely new shape. For instance two triangles put together make a square. Take your children on a walk around the school. Have them point out different shapes to you as they walk (a door is a rectangle, ceiling may form a triangle, etc.) Put as many different shapes (and sizes of shapes) as you can in your dramatic play area. Let you children see that the same shape can be in many different sizes and forms. Everything Preschool >> Themes  >> Shapes >> Science
