It has been a long time since I did chairs with my kids - but here is
what some recent searches turned up - a few people have asked for lesson
plans - but I don't have any -
And I found this cardboard chair challenge - I haven't read through all
of it, but it looks like a class project - those of you looking for more
direction may be able to tweak it for yourselves -

I don't have lesson plans - but these pages may help - and Taschen has a
book called 1000 chairs - it is a good resource. We only made little
models, and it was 5th grade... simple construction with cardboard,
cutters and embellishments -
