https://www.youtube.com/watch?v=04mXcF8FZps (can actually do by hand) or in 3D-https://www.geogebra.org/m/G5gvqWR9, https://www.geogebra.org/m/m5g8DPdJ or
https://www.youtube.com/watch?v=droTYSmSGHg (takes too long to do by hand) but has an interesting reversal: http://math.bu.edu/DYSYS/applets/chaos-game.html (if the game will work as it uses old Java), or use Pascal's Triangle (https://www.youtube.com/watch?v=EE0ODmhiLlA&index=9&list=PLA34565411F0821C0)-which can also be done by hand and Menger Sponge: https://www.youtube.com/watch?v=fWsmq9E4YC0. https://www.youtube.com/watch?v=XMriWTvPXHI/

Origami (some instructions at https://www.youtube.com/watch?v=TKGW2W168H0 for basic piece, then https://www.youtube.com/watch?v=_8ftAKXZ2Rc for what we made). Other instructions at http://www.mathigon.org/origami/ , more instructions at http://www.origami-resource-center.com/modular.html and http://www.origamee.net/diagrams/diagrams.html also shows other items. https://mathcraft.wonderhowto.com/how-to/modular-origami-make-truncated-icosahedron-pentakis-dodecahedron-more-0131528/ shows even more complicated origami (we won't have time to do anything this complicated). We did work in pairs to practice some of the teamwork principles we have talked about earlier in camp.
For week 3. 2018 did a modular spinner: https://www.youtube.com/watch?v=Kl-NxK-y-KY (I believe is the shape)

Activity from a Math Circle, https://www.mathteacherscircle.org/resources/math-sessions/#generalps gives a list of lots of potential activities. A search for Math Circle will likely reveal other math circles who often post their activities. Like contests, finding an activity can be easy, but finding one at the appropriate level of difficulty can be a challenge. We will do a Zome tool (http://www.zometool.com/) activity from http://tgmc.utulsa.edu/archives.html, may do some with 3D nets like those at https://mathigon.org/origami /
