[blindkid] labeling diagrams?

[Rosina Solano]

I have a question about labeling diagrams.  How do the kids do these?
 
Right now the school super enlarges one like a picture of a plant cell.  Then they go over parts of the diagram with glue to make raised parts for the chromosomes, nucleous, etc.  Roman has braille labels to glue onto these areas.  Problem, even though Roman has some vision this is totally inadequate in my line of thinking.  The pictures are diverse, but the glue spots are not, how is he to tell the difference?  Also, the lines that point to the "raised" areas do not have glue on them, so he can't even follow them to the line to put the label on.
Even if this was all raised, I feel there has got to be a better way to label diagrams.  How have any of you done this?  Please really spell things out as I am visually dependant, with no imagination.
 
Thank you so much!!!
