DIY Montessori 100's Board

Adeline has learned to recognize her numbers up to about 20 but not the order, so I have been wanting to work on that.  I really wanted to purchase this neat board on Amazon but now is not the time, so I made one for now.

I found a 100's chart at the Dollar Tree the other day so I cut it up and also purchased a foam poster board.
I laminated the squares and sorted them in groups of ten.  I wrote the first few numbers on because that is what we are working on right now.  I think the matching will help her get started.   I think I need to put a little velcro on yet so that they don't slide around.
