Dear JB,
Congratulations to you both on your new addition! I hope all five of you are getting settled in and enjoying your new darling, getting a little sleep, treasuring this precious time together...there's nothing quite like those wonderful newborn days, when you're all getting to know each other...magical.
Glad your little guy is having so much math fun! Have you looked at Don Cohen's Calculus By and For Young People Age 7 and Up? Harpo had some good times with those books a while back--I've been thinking we should revisit them again. (Cohen's site is
www.mathman.biz ) There is also some fun stuff at
www.mathartfun.com , and also at
www.gnarlymath.com (I even love the site name!).
All good wishes for the surgery next week--do keep us posted if you have a minute, and let us know how he, and you all, are doing!
peace
minnie
