Brown Stairs and Pink Tower Extensions

Here one of my students is building an extension with the pink tower and the brown stair.  He used some picture cards that we printed out from our Montessori classroom guide book.  But you could get extension cards from The Montessori Print Shop http://www.shop.montessoriprintshop.com/Pink-Tower-Broad-Stair-Pattern-Cards-Set-1-SenF-8.htm

Here is a blog that shows pictures of some brown stair and pink tower extensions http://montessoristory.blogspot.com/2012/01/free-pink-towerbrown-stair-extensions.html
