Overview: 
Module 3, Topic G extends to division with three and fourdigit dividends using place value understanding. Students begin the topic by connecting multiplication of 10, 100, and 1,000 by singledigit numbers from Topic B to division of multiples of 10, 100, and 1,000 in Lesson 26. Using unit language, students find their division facts allow them to divide much larger numbers. In Lesson 27, place value disks support students visually as they decompose each unit before dividing. This lesson contains a firstuse script on the steps of solving long division using place value disks and the algorithm in tandem for three and fourdigit dividends (4.NBT.6). Students then move to the abstract level in Lessons 28 and 29, recording long division with place value understanding, first of threedigit, then fourdigit numbers using small divisors. In Lesson 30, students practice dividing when zeros are in the dividend or in the quotient. Lessons 31 and 32 give students opportunities to apply their understanding of division by solving word problems (4.OA.3). In Lesson 31, students identify word problems as a number of groups unknown or group size unknown, modeled using tape diagrams. Lesson 32 allows students to apply their place value understanding of solving long division using larger divisors of 6, 7, 8, and 9. Concluding this topic, Lesson 33 has students make connections between the area model and the standard algorithm for long division.
