Hi, elizabethmom,
Welcome! I hope you will like it here a lot--I've only been around a few months, but I really enjoy this community.
One thing that occurs to me is Julie Brennan's Living Math site (
www.livingmath.net ). She has wonderful lists of "living" (i.e. not textbook/workbook thingys) math books, all sorted chronologically and by topic and approximate level. It's an excellent resource for helping you locate fun math stuff, which might be something you would perhaps enjoy in the summertime. There's a nice blog at
www.funschooling.net with lots of good booklists (strongest in "living" science books, I would say). Maybe a trip to the public library armed with some good lists would get you off to a good start?
Also, since it's going to be summer, maybe some outdoor projects would be fun--map-reading/making, nature sketching, birdwatching, woodworking? You could likely work a little/a lot of math into any of those, I would think!
peace
minnie
