Boogie Boards are a clean, reusable way to practice math problems. It is an LCD eWriter that allows you to write like you would with a pen but the convenience of erasing with the touch of a button. Instead of having to search for a dry erase marker and eraser or purchase new markers because they are misplaced or dried out, boogie boards provide a mess free way of accomplishing the same task. They are a great way to provide immediate feedback to the class and to monitor how well the students are understanding the concept being taught.
