This Instructional Activity is a part of the Lesson 7, Unit 5, Grade 6. This activity continues using partial products and area diagrams to compute products of decimals and connect area diagrams with vertical calculations. In these problems, the side lengths and areas of the rectangle are left blank. Students fill in these fields by decomposing the factors by place value and multiplying them. Like many of the activities in this unit, the work involves understanding the structure of the base-ten system used in multiplication calculations and making sense of it from arithmetic and geometric perspectives.
