The Challenge: Make two different sizes of origami butterflies and then see what you notice and wonder about your pieces!

Materials Needed: At least two different sizes of square paper. (Can be obtained from non-square paper if you ask nicely.) Math conceptsyou could explore with this challenge: angles, proportions/ratio (particularly between length, area, volume)

Instructions below.

Depending on how you use this activity, you may engage with different mathematical standards. I’ve listed possible connected math content above. Here are a few suggestions for how you might integrate the 8 mathematical practices. Feel free to add your own suggestions in the comments!

2.) Reason abstractly and quantitatively. If you double/triple the length of the paper, how does that affect the 3D “volume” of the butterfly created?

5.) Use appropriate tools strategically. What kinds of paper works best for this activity? (Hint: fancy origami paper is not necessary)

7.) Look for and make use of structure. Discuss what it means to be “twice” as big. Consider how that language acts differently when you consider length, area and volume.
