## LET’S BREAK IT DOWN!

### Properties of flat shapes

A circle has no sides and no corners. A triangle has three sides and three corners. A rectangle has four sides and four square corners. A square is a rectangle where all of the sides are the same length.

### Boxes are rectangular prisms.

You see a box. All the faces of the box are shaped like rectangles. This box is a 3D shape called a rectangular prism. A cube has 6 faces that are squares.

### A bucket is a cylinder.

You have a bucket of ice cream. The bucket has a circle at the top and at the bottom. The sides of the bucket are curved. This is a cylinder. A can of soda is also a cylinder.

### Ice cream cones are cones.

We scoop the ice-cream into an ice cream cone. A cone is a 3D shape that has a circle on one end. The other end is pointy. The orange markers on roads are called traffic cones. This is because they are shaped like cones.

## INTRO TO 3D SHAPES DISCUSSION QUESTIONS

### What is a 3D shape?

A 3D shape is a shape that is solid.

### What are examples of spheres?

Some examples of spheres are basket balls, soccer balls, bowling balls, oranges etc. Use classroom examples too.

### What is a cube?

A cube is a solid shape with six faces that are all squares.

### If you rotate a 3D shape or change its size, does it become a different shape?

No, if we rotate a shape, it is still the same shape. If we change the size of the shape, it is still the same shape.

### What shape has a circle on one side and is pointy on the other side?
