Kids’ Project: More Math Calendars?

tulips-by-kuzeytac[Photo by Kuzeytac.]

Several people enjoyed the April calendar and asked if there would be a May version. Unfortunately, my homeschool co-op classes are out until next fall, so I don’t have enough kids to make up problems for me. But if your children would like to send in some puzzles, I will be glad to put another calendar together. If we get enough participation, we could have calendars every month for the rest of the year!

Master these thoroughly, and the rest will follow. What one fool can do, another can.

For years, I have recommended Calculus Made Easy as summer reading (and future reference) for high school or college students headed into a calculus course — and for the parents of those students, who may have studied calculus in ages past and now need to dredge out the dust bunnies of memory so they can help with homework.

The original book (second edition) is now out of copyright and available for free online:

Puzzle: Factoring Trinomials

Factoring Puzzle

My high school class ended the year with a review of multiplying and factoring simple polynomials. We played this matching game, and then I gave them a puzzle worksheet. I liked this idea, but I didn’t like the decoded answer. In my opinion, puzzles should give the student a “reward” for solving them — maybe a joke or riddle or something — but that answer seemed almost like nagging.

So I changed things around to make my own version:
