I have been a Computer Science Teacher for close to 40 years.  I have taught AP Computer Science A and IBH Computer Science.  Although I retired last year after 21 years at Colorado Academy, I still have so many useful materials from teaching that I would love to share with both new and experienced CS teachers.  I am proud of the program I built at Colorado Academy that requires all students to take a programming class as a graduation requirement.  The number of girls taking AP level CS has grown dramatically at the school in recent years.
