The open source algebra textbook

Sarah Hagan's students at Drumright High School in Drumright, Okla., don't use traditional textbooks — they make their own. They begin with blank composition notebooks and each day, Hagan hands out a lesson she's written herself or open-sourced from other teachers across the country. It's usually printed on colored paper and requires some kind of hands-on work: drawing, coloring, cutting. "The point is, we shouldn't have to be like, 'Oh, yeah, there's that chart on page 763 that tells me how to classify something.' They should think, 'Oh, that's on that blue paper that we did a few days ago, and I doodled in the corner,' " Hagan explains. The link in our profile takes you to the full story.
