Make a paper frisbee

15 minutes

You can make a fast-moving frisbee with the help of mathematical shapes.

Requirements

Steps

Step 1

Cut out two 20 x 20 cm squares from two sheets of paper. Cut each of these squares into four smaller squares of 10 x 10 cm. Take the eight squares and fold them into smaller squares, then open these up to make eight small rectangles.

Step 2

Fold the top-left point towards the underside of the fold line, so that a triangle on a square is formed. Then fold the bottom-right point towards the top of the fold line. This will create a parallelogram. Use sticky tape to stick the two triangles to each other. Repeat this for all eight squares.

Step 3

You start making the frisbee by inserting the closed corner of one of the parallelograms into an open side of another parallelogram.

Do this with all eight parallelograms so that you create a circle. Use sticky tape to attach everything. You have now made an octagon.

You’re ready to play with your frisbee!

Step

What did you discover

A parallelogram is a four-sided shape whose opposite sides are parallel to each other and are of exactly the same length. The angles are also always the same size. With the eight parallelograms, you have built an octagon. An octagon is a shape with eight sides and eight angles, which together add up to 1080 degrees.
