And More Mathematical Puzzles to Solve...
A recent review on MathNexus focused on a website full of puzzles involving logic and reasoning with mathematics. It seems that more than a "ton" (i.e. 2000 Google hits) of such websites exist. So, read on for a review of two more I recently discovered...., each with an interesting twist.
First, the web site Chork's Puzzles is unusual in many ways. It is offered as a blog by Chorkie, a student in Singapore. The unusual thing is that he creates his own mathematical puzzles, and some of them are quite good (i.e. rich and challenging). And, since it is a blog, his site includes comments for readers/users as well. If asked a question (e.g. for clarification or for a possible hint), Chorkie will respond. Plus, his web site includes access to solutions of all of his past puzzle creations. I wish more students built web sites such as this...maybe create a new equivalent to Facebook or MySpace...in a mathematical context.
Second, the web site Uncle Bob's Puzzle Corner also is unusual in many ways. It is the creation of Bob Mead, a mathematics teacher in Haverhill, New Hampshire. For seven years prior to this web site, he wrote a monthly column for the Behind the Times, based in Bradford, Vermont. The column included topics from recreational mathematics and gave readers a puzzle or problem to solve. His web site carries on this theme, offering mathematical puzzles both via his web site and through a newsletter (subscription cost is $15). When visiting this web site, be sure to check out the "Free Stuff" and the Puzzle Mall, which encompasses multi-levels of mathematics puzzles covering many content areas over grade levels ranging from elementary through high school. Also, link to the companion web site Uncle Bob and Aunt Claire's Place, where you can find some interesting "mathematics musings" as well as some great recipes. Again, I wish more mathematics teachers built web sites such as this...sharing their favorite mathematics problems and puzzles, as well as revealing insights their students have shown while solving these problems.
