 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...

 Grade 3 Module 2: Place Value and Problem Solving with Units of Measure Module 2 uses place value to unify measurement, rounding skills, and the standard algorithms for addition and subtraction. ...

 Grade 3 Mathematics Module 5: Fractions as Numbers on the Number Line In this 35day Grade 3 module, students extend and deepen second grade practice with "equal shares" to understanding fractions as...

 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 4: Multiplication and Area In this 20day module students explore area as an attribute of twodimensional figures and relate it to their prior understandings of multiplication....

 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...

 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 6: Collecting and Displaying Data This 10day module builds on Grade 2 concepts about data, graphing, and line plots. The two topics in this module focus on generating and analyzing...

 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...

 Students begin by learning to tell and write time to the nearest minute using analog and digital clocks in Topic A (3.MD.1). They understand time as a continuous measurement through exploration with...

 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...

 Topic A opens Module 5 with students actively partitioning different models of wholes into equal parts (e.g., concrete models, fraction strips, and drawn pictorial area models on paper). They...

 More experienced with measurement and estimation using different units and tools, students further develop their skills by learning to round in Topic C (3.NBT.1). They measure, and then use place...

 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...

 In Topic B, students compare unit fractions and learn to build nonunit fractions with unit fractions as basic building blocks (3.NF.3d). This parallels the understanding that the number 1 is the...

 Kilograms and grams are introduced in Topic B, measured on digital and spring scales. Students use manipulatives to build a kilogram and then decompose it to explore the relationship between the...

 Students transfer their work to the number line in Topic D. They begin by using the interval from 0 to 1 as the whole. Continuing beyond the first interval, they partition, place, count, and...

 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...

 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 E, they notice that some fractions with different units are placed at the exact same point on the number line, and therefore are equal (3.NF.3a). For example, 1/2, 2/4, 3/6, and 4/8 are...

 In Topic C, students practice comparing unit fractions with fraction strips, specifying the whole and labeling fractions in relation to the number of equal parts in that whole (3.NF.3d).

 In Topic A, students begin to conceptualize area as the amount of twodimensional surface that is contained within a plane figure. They come to understand that the space can be tiled with unit...

 Students measure and round to solve problems in Topics D and E (3.NBT.1, 3.MD.1, 3.MD.2). In these topics they use estimations to test the reasonableness of sums and differences precisely calculated...
