Free web-based program to send updates to parents and students via text message. They subscribe online and you don't ever have to know their phone numbers and they never have to know yours. Great way to keep kids updated. This is really cool.
Nice for behavior notes, Great for formative assessments and other times so you can remember it later: use address labels, clipboard, and large index cards. Write your notes on the address labels as you walk around and observe. Later, stick them onto the child's index card. Quick and easy! Then, during parent/teacher conferences, just pull out the notecard and share your observations
