This Problem Set is a part of the Lesson 5, Unit 5, Grade 4. In this lesson, students show 1/5 is equal to 2/10 by drawing an area model. Students use an area model to show the decomposition of 1/3 as 4/12 as the sum and product of unit fractions. Students also use an area model to show that 1/2 equals 5/10 and show the decompositions as the sum and products of unit fractions.
