This powerpoint enables teachers to present lessons in long division remotely using a digital checkerboard. The ppt should be used in normal view, not slide show. The teacher can click and drag to rearrange number tiles and bead bars on the checkerboard. This file contains ten checkerboard slides for ease of presentation. Great for distance learning! ( If the Montessori Checkerboard is new to you but you would like you use it, there are many great tutorial videos if one searches the internet!)
