We don't do any formal schooling at home and dd will go to a couple of camps (one is a science camp she was invited to and the other two are just for fun and all are less than a week each). The only thing I have pegged for her this summer is to try to get her to memorize the multiplication tables. She's in 2nd grade, going into 3rd and they are already doing more complicated multiplication (up to 3 digits) but they are not teaching the multiplication tables. I find them very useful in everyday life, so we're going to do that, if we find time when we're not playing.

Other than that, she likes to read and this summer she'll concentrate on reading in Spanish rather than English (she attends a one-way language immersion school) and also in the other language that is spoken at home if we can find some books for her in that language. She is reading a Harry Potter book in Spanish right now and that may take her a while yet. We'll try to get some books in the other language, too, on a trip back to dh's native country.
Mostly, though, we'll swim and play this summer as we do every summer.
