These sturdy paddles make for the perfect tool to keep students involved in class. Have students write down answers or work out problems, then raise the paddle to show their answer. It is a fun, simple way to get students to participate. The double-sided, dry erase feature makes it ideal for review on a test, in-class problems, or a fun activity. The white boards are long lasting and very durable, which is what makes it a great product for years in the classroom. Easy to hold and lift for any age student. One side is blank to write down words or images, while the other side is a graph to let students plot points on the grid. This feature makes it a perfect tool for math and it works for other subjects!
