1. read will receive a string, not an integer
2. use if statements, i.e. if [ $NUMBER -ge 0 ] && [ $NUMBER -le 49 ]; then echo "F"; elif [] && []; then echo "D"; elif...

Case labels are basically simple regex's.

So you might be able to do this

[0-4]*) echo "F”;;
   5*) echo "D”;;
   6*) echo "C”;;
   7*) echo "B”;;
   [89]*) echo "A”;;

But the if/else logic is a bit safer, and more intuitive.
