Occasionally, I get an email or call regarding what resources or textbooks I suggest a district consider. As a state employee of the Department of Public Instruction, I cannot endorse any specific textbook or resource. However, my colleague in Nebraska, Harris Payne, said that he has been sending out the list of vendors who attended NCSS as a way for districts to see who's "out there". I thought that was a great idea!
The vendor list is in alphabetical order, offering a brief overview of resources provided, and contact information.
