HELP!! McGraw Hill Letterbooks, Teacher's Edition I'm supposed to be using the McGraw Hill Letterbooks program with my students this year. For some reason, Title III will only pay for the student editions, even though it's the school's first year using the program. I can't seem to find the teacher's edition anywhere! Does anyone know where I can get one? I've looked through McGraw Hill's catalog, and searched the web, it's as though it doesn't exist, but I know it does! Ideas??
