To the art teacher who was asking about lesson plans for a blind student.
Someone else already mentioned using tactile materials.
In the spirit of a community of Inquiry, have you considered opening this up
to the other students in your class? It would seem to make a for a great
'art' project and a plethora of questions. A few are:
What art, and how, can we make accessible to the sensory deprived or
What forms of art *can* be used by those same people?
Present this to the class and see what they can come up. I should think
that this would encourage the other children to include this child, not as
someone being treated specially by the teacher and with different materials
and lessons, but as a part of their classroom community. As well, this
ought to help the child feel more a part of the community by feeling the
others reach out to him/her.
