I’ve got a bachelor’s degree in advanced math, and a teenager who will tell you he hates anything to do with the subject.

I’m an unschooling parent who loves to do math puzzles and logic problems for fun.

I’m not sure if that combination makes me an expert or just crazy, but because of it, I agreed to take part in the iHomeschool Network’s “5 days of…” series in July 2012 with a look at 5 days of real world math.

These have since become some of the most popular posts on Unschool RULES, and I continue to add more to this topic as we pursue high school using only this approach. So if you’re interested in real world math, read on!
