3-D Shapes

We are learning all about 3-D shape.s The main 3-d shapes we are concentrating on are cubes, cuboids, cylinders and spheres. We identified these shapes in the environment and we also brought in some more examples of these shapes from home. We are practising counting the faces, edges and corners (if applicable) of these shapes. We play a game with teacher where we have to feel a 3-shape in the feely bag (we can't look at it) and we have to feel it and describe what we are feeling. The rest of the class have to guess what shape it is. We give as much information about the shape as possible. For example if we are holding a cube we might say 'the shape in my hand has 6 faces, 12 edges and 8 corners. All the faces are squares. Whoever guesses correctly comes up next and picks another shape from the bag. We also experimented with which 3-d shapes could roll and which ones couldn't. We discovered that the corners aren't helpful when trying to roll a shape with corners!! Cylinders and spheres roll very well whereas cubes and cuboids don't roll at all. We also used 3-d shapes to make things. We worked in groups and had great fun.

I have a cuboid.
