One of the benefits of having kids is that you get to relearn a lot of stuff that you forgot, and learn things that you were never taught when you were in school.
It may sound silly, but I've enjoyed the refresher on long division (when's the last time you did that?), the periodic table of elements and human biology. And while that's basic curriculum for a 5th grader, character development and leadership typically aren't. Except at my daughter's school where they are learning and applying John Wooden's pyramid of success. Knowing the layers of sedimentary rock is certainly important, but Wooden's approach to team and leadership will serve her well for a lifetime.
Check out the official Coach Wooden pyramid of success site. It's chock full of excellent material that anyone in any role can use to improve their individual performance as well as their team's. Honestly it's one of the best sites I've visited in a long time and well worth your time [especially the videos].
P.S. Many thanks to Donna Gamble of Frisco ISD for teaching this great material!
