In this lesson, students will figure out how many different combinations of ice cream flavors and cones they can make. Students will work cooperatively to make the different combinations. They will use various materials to actually make the combinations. The students will also need to include in writing how their group came up with these combinations, and if they noticed any kind of short cut to help them out.This lesson plan was created as a result of the Girls Engaged in Math and Science, GEMS Project funded by the Malone Family Foundation.
