And now the CONE.

Good job!

We need a CUBE and a CUBOID for our foundation.

Oh, hi! Look, we are building a giant roller coaster.

Do you want to help us?

Here comes Benny with shapes.

Benny brought us flat, two dimensional shapes.

Let's unload his wagons.

CIRCLE, OVAL, TRIANGLE

SQUARE, RECTANGLE, RHOMBUS

PENTAGON, HEXAGON, OCTAGON

Thank you, Benny

Donald brought us heavy 3D shapes. You can look at them at any angle.

Let's see what 3D shapes we have

SPHERE

CUBE

CUBOID

CYLINDER

Wow! This is a construction site. Be very careful!

PYRAMID

CONE

Thank you, Donald.

And now let's finish one of the towers.

We've already installed:

CUBOIDS

CUBES

CYLINDERS

And 2D shapes:

CIRCLE

OVAL

TRIANGLE

SQUARE

RECTANGLE

RHOMBUS

PENTAGON

HEXAGON

And OCTAGON

We still need to install: SPHERE, PYRAMID, CONE.

Oh, no! That SPHERE is too small!

Let's try a bigger SPHERE

PYRAMID and CONE

Well done! Another section is built. Soon kids will enjoy this roller coaster.

No! We haven't finished the roller coaster yet!

Help me finish that section.

We need CUBOID

CUBE

and CYLINDERS

Now let's reinforce with these 2D shapes:

CIRCLE, OVAL, TRIANGLE, SQUARE, RECTANGLE, RHOMBUS

Ok, crane...

Ah, oh! Aaaaah!!!

That's fast!

Aaaaah!!!

Lower the section, crane!

We still need PENTAGON, HEXAGON, OCTAGON

SPHERE, PYRAMID and CONE

That was a cool ride!

Thanks for helping me build the roller coaster! Now you know 2D and 3D shapes!
