## 6.EE.A.2a

109 questions4 skills

Write expressions that record operations with numbers and with letters standing for numbers.

## 6.EE.A.2b

85 questions3 skills

Identify parts of an expression using mathematical terms (sum, term, product, factor, quotient, coefficient); view one or more parts of an expression as a single entity.

## 6.EE.A.2c

129 questions7 skills

Evaluate expressions at specific values of their variables. Include expressions that arise from formulas used in real-world problems. Perform arithmetic operations, including those involving whole-number exponents, in the conventional order when there are no parentheses to specify a particular order (Order of Operations).

## 6.EE.A.3

125 questions6 skills

Apply the properties of operations to generate equivalent expressions.

## 6.EE.A.4

108 questions5 skills

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.B.5

112 questions6 skills

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.B.6

53 questions3 skills

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.B.7

222 questions12 skills

## 6.EE.B.8

56 questions3 skills

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.C.9

64 questions4 skills

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.
