This Application Problem is a part of the Lesson 15, Unit 3, Grade 4. Modeling the array (rather than the tape diagram) may give students a clearer picture of the solution to the Application Problem. Encourage students to use the labels photo and page, if beneficial. Discuss how the equation informs the solution, yet the picture reveals the solution. Chandra printed 38 photos to put into her scrapbook. If she can fit 4 photos on each page, how many pages will she use for her photos?
