Origami Geometry!

As a culmination to our geometry unit, we created 
two origami projects!
(Origami is the traditional Japanese art of paper folding.)

One item we created was a beautiful box!

First we colored and cut out a rectangle.

We had to fold it into a smaller rectangle.

Next we opened it up and folded each side into the middle. Do you see the hexagon that was formed?

After that, each corner had to be folded to form an isosceles right triangle.

Can you see the octagon?   

We then folded skinny rectangular flaps over the triangles.

Finally we were able to open it up into a handy box!

Another item we crafted was a clever paper drinking cup!

First, we cut out a square.

Next, we had to fold the square into an isosceles right triangle!

Third, we had to fold to create more triangles.

This had to be done on the other side too!

Can you see the three triangles? One of them is scalene!

Once the flaps were tucked in....

We were able to use our cups!

Which project did you enjoy making the most?
Have you made any other origami items?

  1. Dear Mrs. Ranney and Class,

    Origami geometry is a very exciting activity. My favorite project was creating the rectangular paper box. I have never made other origami items before we did the origami geometry in class last Friday.

    Previously, I made a small, square, paper, folded object out of a larger square paper. When I pull two corners of the square, the paper open and reveals a hexagon shape. If you move the edges slightly, the corners look like the claws on a scorpion.

    I am looking forward to making another project in class soon.
