Grades 1 & up. These engaging, active learning classroom tools are great for games, review, and testing in all subjects. When the paddles are held up, the student's answers are easily seen from anywhere in the room. Each paddle has one blank dry erase side and one lined dry erase side. Easy to store, paddles clean up easily even after extensive use with a damp cloth. Markers store neatly right in the handle. Student pack includes (2) kwik-check paddles with markers and eraser caps.
