Hi! This is our 3rd year hsing. My children are 11, 8 and 2. The oldest two went to ps for 3 years and 1 year, respectively.
This is what we do:
While we went through a no-tv period, we do watch it now. There are a number of programs on Discovery Channel, Animal Planet, HGTV, TLC etc. that my kids have loved and that have sparked an interest in various topics.
I will sometimes ask my oldest to turn the tv off--he seems to be the only one of the 3 who overdoes the tube.
I think that "play" is important -- for everyone, so I wouldn't limit that. I don't give assignments but we do have loads of things around the house for them to do--arts and crafts supplies, pattern blocks, geoboards, board games, card games, science-in-a-box type projects, books and books and books, computer cd's, magazine subscriptions, Legos, puzzles, etc.
I think that if you want them out from in front of the tv, there needs to be an alternative--resources available to them which will spark an interest in other activities, yk?
I am forever suggesting trips, tv programs, articles, games, projects that I think they might be interested in. (Ds is very into construction/architecture as well as the prehistoric world; dd is our artist/mathematician.) Sometimes they're interested, sometimes not. We make weekly (at least) trips to the library. They choose books they want, but I also bring home books about things that I think they'd be interested in and just leave them lying around for the kids to "discover." Although the oldest 2 are readers, I still read aloud to them daily.
As far as university goes, they're too young to be planning for that right now--the most that an admissions office would be interested in would be the "high school" years. If they decide to go to college, I'd help them to research the admission requirements and then map out what they'd need to do to meet them. We talk a lot about different people's careers--it's not important to me that they go to college, but I do hope that they choose a career that they'll enjoy. You know, the whole, "do something you love and it won't seem like work" thing.
My feeling is that, my role is to expose them to lots of different subjects/topics/experiences and then to help them follow their interests. At the moment, we're visiting construction sites, talking to contractors, researching architectural styles and such, because that's where ds' interest is. If, later on, his interest is in going to college, or choosing a high-paying career, I'll help him research and plan for that.
Since I am a product of schooling (rather than unschooling) I sometimes have doubts about what they're up to--that's when I look over my journal. I always ALWAYS am impressed by what they're working on. We don't have worksheets or test scores to file away anywhere, but looking over the journal always helps me to see just how much learning really is going on.
ymmv, but hth!
