# Grade 4 Common Core Math Practice

The focus in Grade 4 is on the following three critical areas:

• Developing understanding and fluency with multi-digit multiplication, and developing understanding of dividing to find quotients involving multi-digit dividends
• Developing an understanding of fraction equivalence, addition and subtraction of fractions with like denominators, and multiplication of fractions by whole numbers
• Understanding that geometric figures can be analyzed and classified based on their properties, such as having parallel sides, perpendicular sides, particular angle measures, and symmetry

### Overview of Grade 4 Standards

#### Operations and Algebraic Thinking

• Use the four operations with whole numbers to solve problems(4.OA.A.1, 4.OA.A.2, 4.OA.A.3)
• Gain familiarity with factors and multiples(4.OA.B.4)
• Generate and analyze patterns(4.OA.C.5)

#### Number and Operations in Base Ten

• Generalize place value understanding for multi-digit whole numbers(4.NBT.A.1, 4.NBT.A.2, 4.NBT.A.3)
• Use place value understanding and properties of operations to perform multi-digit arithmetic(4.NBT.B.4, 4.NBT.B.5, 4.NBT.B.6)

#### Number and Operations—Fractions

• Extend understanding of fraction equivalence and ordering(4.NF.A.1, 4.NF.A.2)
• Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers(4.NF.B.3, 4.NF.B.3.A, 4.NF.B.3.B, 4.NF.B.3.C, 4.NF.B.3.D, 4.NF.B.4, 4.NF.B.4.A, 4.NF.B.4.B, 4.NF.B.4.C)
• Understand decimal notation for fractions, and compare decimal fractions(4.NF.C.5, 4.NF.C.6, 4.NF.C.7)

#### Measurement and Data

• Solve problems involving measurement and conversion of measurements from a larger unit to a smaller unit(4.MD.A.1, 4.MD.A.2, 4.MD.A.3)
• Represent and interpret data(4.MD.B.4)
• Geometric measurement: understand concepts of angle and measure angles(4.MD.C.5, 4.MD.C.5.A, 4.MD.C.5.B, 4.MD.C.6, 4.MD.C.7)

#### Geometry

• Draw and identify lines and angles, and classify shapes by properties of their lines and angles(4.G.A.1, 4.G.A.2, 4.G.A.3)

#### Mathematical Practices

• Make sense of problems and persevere in solving them
• Reason abstractly and quantitatively
• Construct viable arguments and critique the reasoning of others
• Model with mathematics
• Use appropriate tools strategically
• Attend to precision
• Look for and make use of structure
• Look for and express regularity in repeated reasoning
