This file and my word document with the instructions are free, as they only took a matter of minutes to create.
However, there is a $10 Scheduling excel form on my listing that accompanies this form. The two excel files make scheduling students into homerooms much easier.
I know, $10 is a lot. Use your principal's account. It will make you and your counselor's lives much happier.
