We are also unschoolers "at heart" (which means that is the driving philosophy and practice BUT we do some paperwork and "assigned" stuff, mostly math, spelling, writing. But it is by demand of the learner, so imo, it is still unschooling
Today, for example;
my son got into magnets, and we got out his science encyclopedia and read together about them for a while. He drew in his sketch book for a bit, then we went to the thrift store. He explored the place, and went home with a copy of "A Light in the Attic", which he has been reading all afternoon(and is now, aloud, whether we are interested or not, lol!)
Yesterday, we did some multiplication work, read together and alone, went the park for a few hrs and played in the rocks(and encountered many insects and "sticky stuff all over the slides and rocks") This morning, the paper carried an article which answered our questions(what kind of insects are theses? What is all this sticky stuff? (I had suggested that it was some type of "discharge" from insects in the trees, which it was, as it turned out; Giant bark aphids).
We are waiting on our minivan to be repaired so we can make a trip downtown to the zoo/museum/etc. (usually at least 3 times a mth, either just us or with others)
Our schedule is really flexible. Some weeks, we don't "socialize" at all outside the family. Others, we have 2 or 3 excursions/get togethers. I actually initiated a hs group in my area with the goal of meeting others for social stuff; still getting going.
We had him in karate twice a wk at the Y(where I worked until 4 mths ago), and plan to enroll him in it privately this yr as he loves it).
Also, basketball via the Y last yr(possibly again this yr; must buy a membership, now
I am looking into acting classes/participation; our local theatre should offer such a program if they don't. I am going to find out about strarting such a program if it is not already available. The other options are so far away!
Rollerskating once a wk(sometimes with another hs friend, but honestly, they go on "Christian music night" and we'd rather not! But we compromise for their sake
IME, despite all this stuff, there tend to be gaps (like the holidays) when he gets antsy to do more/see others more. But he is pretty demanding in all respects, and requires a great deal of stimulation to feel "satisfied" as a rule! So I temper my "guilt" with realism, lol! (I have a 2 yr old, so that restricts us some, and wears me out some more
ITA that, as John Holt said, "If there were no other reason to keep your kids out of school, the socialization they receive there would be reason enough." Sorry, but most children I know in such settings are not the friends I would choose for my children; very trend/marketing driven, shallow, generally isolated from parents/family/themselves. JMO.
I do not believe that near constant "socialization" with peers is nec. or beneficial; in many cases, such segregated conditions result in pathological conditions (teasing, pecking order, bullying, peer pressure, etc). Whereas being able to interact with others of all ages is a wonderful thing not often cultivated in our institutional settings. A few days a week is plenty, imo and exp.
But we are often pushed to think otherwise. Kimberly, mom to Forest, 9 and Lily, 2 (BTW, IMO as a former preschool teacher for 10 yrs, 5 yrs old is WAY young to worry about either academics or socialization in any formal sense! Just take him with you and engage him/allow him to engage the world around him, incl. people of all ages. He will be more capable than most of interacting with those his own age and others!
