cooperative learning classroom model Versatile Configurations The shape of the desks allow many types of configurations in a classroom setting. The leg shape allows freedom of movement under the desks. Also take a look at look at the snazzy computer renderings that I did to show multiple desk groupings. Grouping of 3 Desks The rotating chalkboard will mount on the desks in both groups of three desks as shown or groups of four desks. For further explaination about the desk, chair or chalkboard take a look at the parts of the system. Grouping of 4 Desks Adding a fourth desk does not push the members of the group further apart. The inward curve of the worksurface when configured in groups of four desks allows the students to stay within an acceptable interaction distance.
