Overview: 
Building on their work in Module 3, Topic B, students begin in Topic C decomposing numbers into base ten units in order to find products of singledigit by multidigit numbers. Students practice multiplying by using models before being introduced to the standard algorithm. Throughout the topic, students practice multiplication in the context of word problems, including multiplicative comparison problems. In Lessons 7 and 8, students use place value disks to represent the multiplication of two, three, and fourdigit numbers by a onedigit whole number. Lessons 9 and 10 move students to the abstract level as they multiply three and fourdigit numbers by onedigit numbers using the standard algorithm. Finally, in Lesson 11, partial products, the standard algorithm, and the area model are compared and connected via the distributive property (4.NBT.5).
