Create New Shapes From Existing Ones
What you will learn from this videoWhat you will learn
- We'll learn how to put together 2D shapes to make new shapes.
- We’ll also learn how to make 3D shapes from 2D shapes.
- And we'll explore how this knowledge can help us make origami, quilts and even pizza!

Discussion Questions
- Before Video[Hold up or draw a square.] What shape is this? How do you know?ANSWER
It’s a square because it has four square corners and four sides all the same length.
It’s a triangle because it has three sides.
It’s also a triangle because it also has three sides.
It’s a cube because it is a 3D shape with six square faces.
It’s a cylinder because it is a 3D shape with circles on both ends.
- After Video[Hold up or draw two identical right triangles with all three sides of different lengths.] How can you use these shapes to make a rectangle?ANSWER
Put the two triangles next to each other with the long sides together.
Put the two rectangles together. You can put the long sides together or the short sides together.
Put the triangles together. The middle triangle is upside-down compared to the other two triangles.
A rectangular prism.
Stack all three cylinders together so the circular faces line up.

Review flat shapes.
Circles, triangles, rectangles, squares, and hexagons are all flat shapes. A circle is a round shape with no sides or corners. A triangle has 3 sides. A rectangle has 4 sides and 4 square corners. A square is a special type of rectangle with all sides the same length. A hexagon has 6 sides.

You have quilt patches that are squares and triangles. What shapes can you make? You could put 1 square and 2 triangles together to make a new shape, called a trapezoid. Then, you could put two trapezoids together to make another new shape, a hexagon.
