Group D. Groups A and B have the same number of subs, but Group A has more people, so they have less to eat. So Group B can be eliminated. Group C is sharing two subs among three people. Therefore, the people in Group A have the least to eat. Overview Students investigate four situations in which different-sized groups of students want to equally divide a certain number of submarine sandwiches.
Students determine in which groups a student gets the most and the least to eat.
The problems on this page informally introduce students to the concept of fractions. Some students may use fractions explicitly to solve these problems. Others may simply compare the number of students to the number of submarine sandwiches in each group to divide the subs equally. Planning You might introduce the context of this section with a brief discussion using one or more of the suggestions from the Planning Instruction section on page 5 of the Teacher Guide. Have students work individually on problems 1 and 2 and then share their solutions and strategies with a partner or small group.
