 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 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 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 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 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...

 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 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...

 Students fold fraction strips, then shade in the units.

 Students cut a rectangular shape into 6 equal units. They show three different ways of cutting it.

 Students use choral response in fluency activities involving fractions. The teacher says a fraction and the students say the other part of one whole. Students skip count by 1 tenth using fractions...

 This Mathematics Common Core video features third grade students from John F. Kennedy Intermediate School located in Deer Park, Long Island. The lesson demonstrates Focus Standard 3.MD.8: Solve real...

 Objective: Decompose fractions using area models to show equivalence.

 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...

 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...

 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...

 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 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...

 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...

 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...

 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...

 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...

 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...

 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...

 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...
