This Application Problem is a part of the Lesson 4, Unit 7, Grade 3. Modeling a tape diagram for the money fourth graders raise, as well as the total money raised, helps English language learners and students working below grade level better grasp the meaning of the phrase $68 less than the third graders. Ask, "Who raised less money? Did the fourth graders raise $68? Use the model to estimate about how much the fourth graders raised."
