Ratios and Proportional Relationships
Understand ratio concepts and use ratio reasoning to solve problems.
6.RP.1 Understand the concept of a ratio and use ratio language to describe
a ratio relationship between two quantities.
6.RP.2 Understand the concept of a unit rate a/b associated with a ratio a:b
with b ≠ 0, and use rate language in the context of a ratio relationship.
6.RP.3 Use ratio and rate reasoning to solve real-world and mathematical problems,
e.g., by reasoning about tables of equivalent ratios, tape diagrams, double number line diagrams, or equations.
The Number System
Apply and extend previous understandings of multiplication and division to
divide fractions by fractions.
Compute fluently with multi-digit numbers and find common factors and multiples.
Apply and extend previous understandings of numbers to the system of rational
numbers.
6.NS.1 Interpret and compute quotients of fractions, and solve word problems
involving division of fractions by fractions, e.g., by using visual fraction models and equations to represent the problem.
6.NS.2 Fluently divide multi-digit numbers using the standard algorithm.
6.NS.3 Fluently add, subtract, multiply, and divide multi-digit decimals using
the standard algorithm for each operation.
6.NS.4 Find the greatest common factor of two whole numbers less than or equal
to 100 and the least common multiple of two whole numbers less than or equal to 12. Use the distributive property to express
a sum of two whole numbers 1–100 with a common factor as a multiple of a sum of two whole numbers with no common factor.
6.NS.5 Understand that positive and negative numbers are used together to
describe quantities having opposite directions or values (e.g., temperature above/below zero, elevation above/below sea level,
credits/debits, positive/negative electric charge); use positive and negative numbers to represent quantities in real-world
contexts, explaining the meaning of 0 in each situation.
6.NS.6 Understand a rational number as a point on the number line. Extend
number line diagrams and coordinate axes familiar from previous grades to represent points on the line and in the plane with
negative number coordinates.
6.NS.7 Understand ordering and absolute value of rational numbers.
6.NS.8 Solve real-world and mathematical problems by graphing points in all
four quadrants of the coordinate plane. Include use of coordinates and absolute value to find distances between points with
the same first coordinate or the same second coordinate.
Expressions and Equations
Apply and extend previous understandings of arithmetic to algebraic expressions.
Reason about and solve one variable equations and inequalities.
Represent and analyze quantitative relationships between dependent and independent
variables.
6.EE.1 Write and evaluate numerical expressions involving whole-number exponents.
6.EE.2 Write, read, and evaluate expressions in which letters stand for numbers.
6.EE.3 Apply the properties of operations to generate equivalent expressions.
6.EE.4 Identify when two expressions are equivalent (i.e., when the two expressions
name the same number regardless of which value is substituted into them).
6.EE.5 Understand solving an equation or inequality as a process of answering
a question: which values from a specified set, if any, make the equation or inequality true? Use substitution to determine
whether a given number in a specified set makes an equation or inequality true.
6.EE.6 Use variables to represent numbers and write expressions when solving
a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose
at hand, any number in a specified set.
6.EE.7 Solve real-world and mathematical problems by writing and solving equations
of the form x + p = q and px = q for cases in which p, q and x are all nonnegative rational numbers.
6.EE.8 Write an inequality of the form x > c or x < c to represent a
constraint or condition in a real-world or mathematical problem. Recognize that inequalities of the form x > c or x <
c have infinitely many solutions; represent solutions of such inequalities on number line diagrams.
6.EE.9 Use variables to represent two quantities in a real-world problem that
change in relationship to one another; write an equation to express one quantity, thought of as the dependent variable, in
terms of the other quantity, thought of as the independent variable. Analyze the relationship between the dependent and independent
variables using graphs and tables, and relate these to the equation. For example, in a problem involving motion at constant
speed, list and graph ordered pairs of distances and times, and write the equation d = 65t to represent the relationship between
distance and time.
Geometry
Solve real-world and mathematical problems involving area, surface area, and
volume .
6.G.1 Find the area of right triangles, other triangles, special quadrilaterals,
and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context
of solving real-world and mathematical problems.
6.G.2 Find the volume of a right rectangular prism with fractional edge lengths
by packing it with unit cubes of the appropriate unit fraction edge lengths, and show that the volume is the same as would
be found by multiplying the edge lengths of the prism. Apply the formulas V = l w h and V = b h to find volumes of right rectangular
prisms with fractional edge lengths in the context of solving real-world and mathematical problems.
6.G.3 Draw polygons in the coordinate plane given coordinates for the vertices;
use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate.
Apply these techniques in the context of solving real-world and mathematical problems.
6.G.4 Draw polygons in the coordinate plane given coordinates for the vertices;
use coordinates to find the length of a side joining points with the same first coordinate or the same second coordinate.
Apply these techniques in the context of solving real-world and mathematical problems.
Statistics and Probability
Develop understanding of statistical variability.
Summarize and describe distributions.
6.SP.1 Recognize a statistical question as one that anticipates variability
in the data related to the question and accounts for it in the answers.
6.SP.2 Understand that a set of data collected to answer a statistical question
has a distribution which can be described by its center, spread, and overall shape.
6.SP.3 Recognize that a measure of center for a numerical data set summarizes
all of its values with a single number, while a measure of variation describes how its values vary with a single number.
6.SP.4 Display numerical data in plots on a number line, including dot plots,
histograms, and box plots.
6.SP.5 Summarize numerical data sets in relation to their context.
