This is the traditional Montessori teens board, as made by Nienhuis. 
Here's my slightly avant-garde Teens Board. I had some nice & thick card stock pieces and decided to make it in an accordion style. While, it's very cute & stores nicely I'll have to evaluate that design decision down the track.
Here it is unfolded.
And, on the back. I taped alternate sides of the card & rubbed a candle over the exposed seams so that they won't get dirty.

Hmmm, I just tried to attach the pdf's but don't seem to be able to work out how to do that in blogger (any tips?) so please leave me a comment with your email address if you would like them.
