As I was searching the other day, I came across two great sites chock full of information from teachers near and far. There are many different games, activities, resources, and technology that comes from the classroom in these two blogs.
The first is http://www.greatmathsteachingideas.com/ which are teaching ideas for the math classroom. It goes over certain concepts and different uses of technology in the classroom. There are new and different study cards for students to practice.
The second is http://mrbartonmaths.com/ gives teachers, students, and parents tips on software, resources, and reviews of math products. This is a great site.
