I wasn't that impressed with them: they were mostly arithmetic - not actual math.
Same request as the friendly request above to which I responded: what resources would you suggest for examples of "actual math" appropriate for elementary-age students.
I use a great variety of problem sources, published in both English and Chinese, to teach various learners of elementary math supplementary lessons, which is my current occupation. But one can never have too many sources of problems, so what sources do you suggest? There's no "ceiling" of difficulty level, because I have early-elementary-age students who are already well along in secondary-level math, so I have to keep looking for more challenging material all the time for my most advanced students.
Hmm, that's a fair question. I tutored high school kids (14-17) for a while, and I would generally tailor things to their interest.
Basically, I tried to relate the math to solving a real problem they might be interested. Limits to money problems (e.g., could you retire on a Million dollars? Now take into account inflation, interest, etc)., differentials to sports/computer-games (plot the trajectory of the ball), random riddles, etc.
I'm not really sure how well that would translate to younger kids though ... My elementary school aged nephews/nieces tend to enjoy geometry problems (find the pattern ...), 'shortcuts' (FOIL, etc), and morphisms, but I fear my experience with kids that young is too limited to draw any general conclusions.
I wish I had access to people who were really good at problem solving when I was in my pre-university days. The intention is not to really become an ace problem solver, but to give the brain a real good workout.
I concur with the recommendation of the Art of Problem Solving website for all ages of problem-solvers. That's where I first took up the screen name I also use here on HN.
