Hi,
Are there any local scout groups or sports clubs that your ds might enjoy? my dd is an only child with no close family. i have found that HE offers her a chance to have friends who have similar interests to her, regardless of their age, rather than forcing her to find friends among a group of kids the same age who happen to live nearby. she loved school and was popular, but honestly has more friends now than before, and their ages range from 3 to 16!
we found a local dance school that offers a variety of classes and, because she can sleep in of a morning, she has the energy to do 6 hours of classes per week (and it's reasonably priced too thank god!)
We also get together with our lcoal HE groups for activities. go on yahoo groups and search for HE xx area to find out what is going on near you.
While children are at school for 6 hours a day, they are not learning for that entire time. You can probably cover the same amount of work in an hour of one-to-one tutoring. When a child is off school sick, the Local Authority is obliged to provide five hours home tuition per week as this is considered sufficient to keep them up to date with their classmates.
I like a structured approach to learning, i have a timetable and get flustered without a routine. That said, we rarely do more than 3 hours structured learning per day. obviously, dd is learning the whole time, but we just aren't sitting down at the table with workbooks.
I really wouldn't worry about your son's writing, he will discover it in his own time. that's the joy of HE - YOU set the curriculum. my dd is 9 and we've only been HE since last september. we use proper workbooks for maths and english but everything else is led by what she wants to learn. we do a topic per half term (like reptiles, WW2, space, the brain).
i started off setting her a book to read each week but found that some weeks she wasn't interested. so, rather than nag her, i stopped it and now she reads when she feels like it. some weeks she might not read much but then others (like this week) she's on her second book already!!!
I've found that our HE 'style' has relaxed a lot over the past few months, especially with the sunny weather. but i know that dd is still learning all the time (even playing on the wii is hand-eye coordination etc) and, more importantly, she is having fun.
i don't know about teaching more than one but i would imagine that you could set work at appropriate levels at do it at the same time, say have a maths session, then english, then art etc.
oh dear, i've gone on again haven't i.
