Pilot mathematicians are doing a wonderful job exploring three-dimensional figures. We are currently working with cubes, cylinders, cones, and spheres.
We continue to work on naming and identifying these objects. Today we went a step further and discussed how these figures will move. Will they roll or slide? We used tape to mark the start and finish line. Before we began we discussed each figure. Does it have flat sides, or is it round? Does it have both flat and round surfaces?

We used tape to mark the start and finish line. Before we began we discussed each figure. Does it have flat sides, or is it round? Does it have both flat and round surfaces?
We made a prediction then tested our hypothesis. Here is what we found:
Cube: The cube does not roll because it has flat sides. When we push the cube it slides across the tape.
Sphere: Round on all sides, the sphere roles when pushed.
Cone: When placed on the flat bottom the cone is able to slide from start to finish. When placed on its side the cone will roll in a circle. It can not roll in a straight line from start to finish like a sphere.
Cylinder: When placed on the top or bottom flat surfaces the cylinder will slide. If the cylinder is turned on its rounded side it will roll! Wow, what a dynamic figure!
