Mr. phillips is grouping his fifth-grade students for a cooperative learning project that will span class periods for two weeks. he has 5 groups of four plus one group of three. he balanced the number of boys and girls in the groups and made sure the students who are perceived by their peers to be different were placed in a group together. what does he need to change about his groups? he has grouped them appropriately and needs to change nothing. increase the size of the groups to five or six students per group. group boys and girls separately at this age. place a student who is different in a group with a student who is tolerant.
