Big Binomial Blocks

Hi all,

 Has anyone seen these huge Montessori binomial/trinomial

cubes in your training? I came across them from a german training

program. They could be d.i.y. project with  craft wood or card board

and painted.  I thought they'd be a great intro for toddlers.

I also saw a larger than usual homemade set at

http://donnamarie.wordpress.com/2007/06/25/making-a-binomial-and-trinomial-cube/ with instructions (ratios).

I love all of Montessori's cubes...one of these days

I'll own all the powers of the binomial! So beautiful.

I will post up the pictures just to enjoy along with a

link list of resources.
