Math - I know it's awesome!
Teaching Math With Songs
FREE powerpoint games you can modify: Jeopardy, Wheel of Fortune, Millionaire,etc.
I LOVE this online lesson planning website. As you create a lesson plan, you note what Common Core Standards apply via a dropdown menu. As a middle school teacher, I create a section for each of my periods and save the documents in the file. So snazzy and FREE! Love it!
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.
Throw dice in with any math station and kids are pumped - here's a ton of dice games!
