I really should be studying for my teaching license math exam and writing about it, but eh….no thanks!
I think I have reviewed my calculus enough, know my weakness with combinatorics, and that I need to make sure to multiply or divide by two when solving some geometry problems.
So what am I thinking about instead? Riddles. If you have never done so, google ted ed riddles. I guarantee you will find plenty of material to occupy your time. And if you are a teacher, you fill find some last days of school material to engage your students.
Today, I got to solve the river crossing riddle. 
As they say in England…Give it a go!
