Content Quality
Rating:
Strengths:
This site contains a very large collection of very challenging math problems. Information (one star to five stars is given about the difficulty). Each problem has a link to a hint and a link to the fully worked out solution. The problems come from diverse areas of mathematics, the hints provide a key step, and the solutions are easy to follow.
Concerns:
The puzzles are all of a high to severe level of difficulty. Even the one star problems are quite difficult. This is not indicated on the main page and students could become discouraged about mathematics if they are not able to do any of the problems.
Potential Effectiveness as a Teaching Tool
Rating:
Strengths:
The “About” page provides information about the site and instructs the user how to use the hints and solutions. The reference to “teaching tool” is less relevant for this site, as it would not be used in a particular class. It will be used by students who want a math challenge or for math contests.
Concerns:
None
Ease of Use for Both Students and Faculty
Rating:
Strengths:
It is easy to jump in and work on puzzles from this site. The navigation is easy and the instructions are clear.
Concerns:
Each individual puzzle solution/hint/answer page could use a “Back” button that would take a user back to the statement of this particular puzzle.
