Good clear instructions 
Was just wondering what are sandpaper letters? I have never heard of them before.
Cheers
I have never seen them ,but I assume they are letters cut from sandpaper and pasted onto card stock. That way a child not only sees the letter, but can also feel how it is formed.
could not be a usual sandpaper. once I gave a peace of sandpaper to my doughter (18 months) and she imediately tried to test it with her teath. :(:(
it’s cool, I have to try to find sandpaper somewhere 
here in Italy it’s a little difficoult with special cards, paper for these activities and strange that Montessori lived here :huh:

Interesting idea. Not sure what I think about it yet. It certainly meets a multi-sensory standard.
