Welcome Students and Parents

Welcome students and parents to IS 141 and the school year 2009-2010.  It’s going to be an exciting year.  We will use this site for many things during the year.  This is where homework is posted and special assignments are explained. It’s also a source of reference  and a place to find test prep material. I encourage comments and questions, and try to respond in a timely fashion.

Please look around the site and leave comments or questions.

Thank you,

Mr. Hoffner
