Flexagons

Made out of paper, a flexagon can be folded into itself for what seems like an infinite loop, but is actually just 4 repeating frames. Combined with colors and storytelling, they can be a great way to explore different subjects through paper engineering.

Included with the instructions are 3 templates to use along with classroom activity inspiration.

How to set up a flexagon:

Depending on different factors of your classroom, you may choose to prepare steps 1-5 ahead of time for your students.

Materials:

  • Printer
  • Card stock (a sturdy weight like 80g)
  • Scissors (or craft knife with a metal ruler)
  • Glue stick
  • Art supplies for adding color and details

Here is a quick video going over the same steps that are typed up below with images.

Step 1: Print

I have provided 3 flexagon templates, the first one is blank, and one- sided. The human body and tree templates are two-sided and I recommend using the Printer Instructions for a successful print.

Step 2: Cut

Cut around the outer edge of the rectangle.

TIP: When cutting the outside line, make sure to cut the black line off, or it will make a reappearance in the final piece.

The cut line is highlighted in green.

Step 3: Slice smaller cut lines

Carefully cut all the solid lines that are highlighted in the image below.

TIP: Make sure to not cut all the way to the edge. There needs to be a little bit of paper left. Only cut where there is a solid line.

The cut lines are highlighted in green.

Step 4: Fold

Fold the outside edges toward the center, crease on the dotted lines.

TIP: Use your fingernail or the side of a credit card to flatten the fold further.

The fold lines are highlighted in green.

Step 5: Glue

Use a glue stick to coat the solid grey rectangles with glue, and then re-fold the edges to the center that you made in Step 4.

The glue areas are highlighted in light green.

Step 6: Train it

After the glue is dry, start folding through the frames until it starts to flow more smoothly.

Step 7: Add Color

For my example, I drew the life cycle of a seed. The video below shows my process of how I decided what to draw on each frame, and the end result.
