Hi, I was recently hired as a middle school science teacher in Newark, NJ. I received a call on a Friday and was asked to begin the following Monday. As a new teacher, and with only 3 days to prepare, I was really feeling the pressure. The school requires 2 weeks of lesson plans every Sunday, so I began searching the web for help. Thank goodness I found Lesson Planet. I still use the site everyday to form great lessons and activities for the kids.
