Elizabethmom, we're in a similar situation with DS6 (1st) who goes to an all day pull out about 1x every 6 school days. We do a lot of informal unschooling at home and during this summer we'll likely (loosely) go through Life of Fred math books and other things. Maybe so some advanced biology (an interest) but it'll all be very informal and flexible. We'll definitely visit several museums as time permits.

FWIW.
