I found the ideas for these slotted building discs at Made by Joel and thought it was a great project to share with all of you. I love the idea of taking these along with you for a quiet activity for the kids.
These are simple to make. All you have to do is print out the two templates provided and cut them out. Show the kids how to connect the discs together using the slots you cut.
