Colorado Grade 5 Math Standards
The official Colorado Grade 5 math standards, grouped by domain with the exact code and description for each expectation.
5.OA · Operations & Algebraic Thinking
- 5.OA.AOperations & Algebraic Thinking: Write and interpret numerical expressions
- 5.OA.A.1Use grouping symbols (parentheses, brackets, or braces) in numerical expressions, and evaluate expressions with these symbols
- 5.OA.A.2Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them
- 5.OA.BOperations & Algebraic Thinking: Analyze patterns and relationships
- 5.OA.B.3Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane
5.NBT · Number & Operations in Base Ten
- 5.NBT.ANumber & Operations in Base Ten: Understand the place value system
- 5.NBT.A.1Recognize that in a multi-digit number, a digit in one place represents 10 times as much as it represents in the place to its right and 1/10 of what it represents in the place to its left
- 5.NBT.A.2Explain patterns in the number of zeros of the product when multiplying a number by powers of 10, and explain patterns in the placement of the decimal point when a decimal is multiplied or divided by a power of 10. Use whole-number exponents to denote powers of 10
- 5.NBT.A.3Read, write, and compare decimals to thousandths
- 5.NBT.A.4Use place value understanding to round decimals to any place
- 5.NBT.BNumber & Operations in Base Ten: Perform operations with multi-digit whole numbers and with decimals to hundredths
- 5.NBT.B.5Fluently multiply multi-digit whole numbers using the standard algorithm
- 5.NBT.B.6Find whole-number quotients of whole numbers with up to four-digit dividends and two-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models
- 5.NBT.B.7Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used
5.NF · Number & Operations—Fractions
- 5.NF.ANumber & Operations-Fractions: Use equivalent fractions as a strategy to add and subtract fractions
- 5.NF.A.1Add and subtract fractions with unlike denominators (including mixed numbers) by replacing given fractions with equivalent fractions in such a way as to produce an equivalent sum or difference of fractions with like denominators
- 5.NF.A.2Solve word problems involving addition and subtraction of fractions referring to the same whole, including cases of unlike denominators, e.g., by using visual fraction models or equations to represent the problem. Use benchmark fractions and number sense of fractions to estimate mentally and assess the reasonableness of answers
- 5.NF.BNumber & Operations-Fractions: Apply and extend previous understandings of multiplication and division
- 5.NF.B.3Interpret a fraction as division of the numerator by the denominator (a/b=a÷b). Solve word problems involving division of whole numbers leading to answers in the form of fractions or mixed numbers, e.g., by using visual fraction models or equations to represent the problem
- 5.NF.B.4Apply and extend previous understandings of multiplication to multiply a fraction or whole number by a fraction
- 5.NF.B.5Interpret multiplication as scaling (resizing), by:
- 5.NF.B.6Solve real-world problems involving multiplication of fractions and mixed numbers, e.g., by using visual fraction models or equations to represent the problem
- 5.NF.B.7Apply and extend previous understandings of division to divide unit fractions by whole numbers and whole numbers by unit fractions. (Students able to multiply fractions in general can develop strategies to divide fractions in general, by reasoning about the relationship between multiplication and division. But division of a fraction by a fraction is not a requirement at this grade.)
5.MD · Measurement & Data
- 5.MD.AMeasurement & Data: Convert like measurement units within a given measurement system
- 5.MD.A.1Convert among different-sized standard measurement units within a given measurement system (e.g., convert 5 cm to 0.05 m), and use these conversions in solving multi-step, real-world problems
- 5.MD.BMeasurement & Data: Represent and interpret data
- 5.MD.B.2Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). Use operations on fractions for this grade to solve problems involving information presented in line plots
- 5.MD.CMeasurement & Data: Geometric measurement: Understand concepts of volume and relate volume to multiplication and to addition
- 5.MD.C.3Recognize volume as an attribute of solid figures and understand concepts of volume measurement
- 5.MD.C.4Measure volumes by counting unit cubes, using cubic cm, cubic in, cubic ft, and improvised units
- 5.MD.C.5Relate volume to the operations of multiplication and addition and solve real-world and mathematical problems involving volume
5.G · Geometry
- 5.G.AGeometry: Graph points on the coordinate plane to solve real-world and mathematical problems
- 5.G.A.1Use a pair of perpendicular number lines, called axes, to define a coordinate system, with the intersection of the lines (the origin) arranged to coincide with the 0 on each line and a given point in the plane located by using an ordered pair of numbers, called its coordinates. Understand that the first number indicates how far to travel from the origin in the direction of one axis, and the second number indicates how far to travel in the direction of the second axis, with the convention that the names of the two axes and the coordinates correspond (e.g.,x-axis andx-coordinate,y-axis andy-coordinate)
- 5.G.A.2Represent real-world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the context of the situation
- 5.G.BGeometry: Classify two-dimensional figures into categories based on their properties
- 5.G.B.3Explain that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles
- 5.G.B.4Classify two-dimensional figures in a hierarchy based on properties
5.1
- 5.1Number and Quantity
5.2
- 5.2Algebra and Functions
5.3
