This Instructional Activity is a part of the Lesson 8, Unit 8, Grade 7. In this activity, students find the number of different sandwiches that can be made from available options. Explain to students that the sandwich makers are instructed to put a certain amount of each item on the sandwich for each selection. Therefore, if a person really loves tomatoes, he should ask for tomatoes twice as his two veggie choices. Give students 5 minutes of quiet work time followed by a whole-group discussion.
