my favorite addition math stations. This one is called "in and out". The students simply drop a handful of cubes onto the in and out board. They record the number in the circle for the first addend and the cubes outside of the circle as the 2nd addend. Then solve the number sentence. The kids really like it!
Sites that I can't do without as a math teacher (and what's so special about each one!) Links to virtual manipulatives, discovery-based lessons, free graphing software, question prompts, eBooks, and more.... Tons of resources for math teachers
