I maintain this web site on my own equipment and at my own expense for the benefit of eighth grade math students and teachers at Hillsdale Middle School, part of the Cajon Valley Union School District in the eastern part of San Diego County.
I do not set district policy, nor do I speak for the district outside my limited role as a math teacher at one site. If you need to speak to someone who does set policy, or who is authorized to speak for the district, let me know and I will place you in contact with the correct person. Of course, if you read anything on this site that conflicts with district policy, go with the district policy, and please let me know so I can correct my site.
