Problem Set 2 for my Problem-Solving Course

I've posted problem set 1 here and Chapter 0, which I've renamed Unit 1, here. Both are going to be part of a workbook I am creating for my students in my Honors Problem-Solving seminar. Thanks a million to @mrdardy for catching some typos and asking me great and thoughtful questions!


Here is my Problem Set 2.

In the 6 problems I give each week, I’m trying to include (and this has pretty much been in my head till now…I blogged about some of it, or wrote in the comments):

-one algebra problem

-one geometry problem

-one probability problem

-one problem based on what I will be doing in class that week

-one problem that may “recur” that they could see again somehow (like, my second problem set has a geo problem that ends up being the golden ratio)

-one logic problem

I think I have to write my weekly unit 2 before I create the next problem set, so it will all fit in well together...in other words, the unit and the problem sets kind of go hand in hand. 

Speaking of hands, below is the logic problem from problem set 2. 

Any feedback is welcomed :)
