This Application Problem is a part of the Lesson 1, Unit 5, Grade 4. This Application Problem reviews and reinforces the concept that fractional parts have the same area. Many students may say that the diagonal lines do not create fourths because the triangles created by the diagonals do not look alike. Exploration helps students see that the areas are, in fact, equal and prepares them for the work with tape diagrams that is done in this lesson.
