 Topic A begins with solving one and twostep word problems based on a variety of topics studied throughout the year, using all four operations (3.OA.8). The lessons emphasize modeling and reasoning...

 In Topic F, students multiply by multiples of 10 (3.NBT.3). To solve a fact like 2 × 30, they first model the basic fact 2 × 3 on the place value chart. Place value understanding helps them to...

 In Topic E, students begin by working with facts using units of 0 and 1. From a procedural standpoint, these are simple facts that require little time for students to master; however, understanding...

 Topic D introduces units of 9 over three days, exploring a variety of arithmetic patterns that become engaging strategies for quickly learning facts with automaticity (3.OA.3, 3.OA.7, 3.OA.9). Nines...

 Topic C anticipates the formal introduction of the associative property with a lesson on making use of structure to problem solve. Students learn the conventional order for performing operations...

 Topic B introduces units of 6 and 7, factors that are well suited to Level 2 skipcounting strategies and to the Level 3 distributive property strategy, already familiar from Module 1. Students...

 Topic A begins by revisiting the commutative property. Students study familiar facts from Module 1 to identify known facts using units of 6, 7, 8, and 9 (3.OA.5, 3.OA.7). They realize that they...

 Topic F introduces the factors 5 and 10, familiar from skipcounting in Grade 2. Students apply the multiplication and division strategies they have used to mixed practice with all of the factors...

 Topic E shifts students from simple understanding to analyzing the relationship between multiplication and division. Practice of both operations is combined—this time using units of 4—and a lesson...

 In Topic D students model, write and solve partitive and measurement division problems with 2 and 3 (3.OA.2). Consistent skipcounting strategies and the continued use of array models are pathways...

 In Topic C, students use the array model and familiar skipcounting strategies to solidify their understanding of multiplication and practice related facts of 2 and 3. They become fluent enough with...

 Study of factors links Topics A and B; Topic B extends the study to division. Students understand division as an unknown factor problem, and relate the meaning of unknown factors to either the...

 Lessons in Topic A move students toward understanding familiar repeated addition from Grade 2 in the form of array models, which become a cornerstone of the module. Students use the language of...

 Grade 3 Module 7: Geometry and Measurement Word Problems This 40day final module of the year offers students intensive practice with word problems, as well as handson investigation experiences with...

 Grade 3 Module 3: Multiplication and Division with Units of 0, 1, 6–9, and Multiples of 10 This 25day module builds directly on students’ work with multiplication and division in Module 1. Module 3...

 Grade 3 Module 1: Properties of Multiplication and Division and Solving Problems with Units of 2–5 and 10 This 25day module begins the year by building on students’ fluency with addition and...
