Not having enough materials/resources is a common complaint among teachers. I love following how a young teacher in rural Oklahoma, Sarah Hagan, is finding a way to thrive without using textbooks. Back in March NPR did a feature story about Sarah titled " The Teacher Who Believes Math = Love."
Since hearing that story, I have been a regular follower of her blog Math = Love. If you ever need tips on how to make the classroom interactive or how to help students create their own textbooks, then look no further. She updates her blog almost daily (where she finds the time, I have no idea) and she is truly passionate about her students and how she can help them learn.
