**6.EE.2**- Write, Read and Evaluate expressions in which letters stand for numbers.

6.EE.A.2aWrite expressions that record operations with numbers and with letters standing for numbers.For example, express the calculation “Subtract y from 5” as 5 – y.

6.EE.A.2bIdentify 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.2cEvaluate 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).For example, use the formulas V = s.^{3}and A = 6 s^{2}to find the volume and surface area of a cube with sides of length s = 1/2

Evaluate Expressions

**6.EE.3**- Apply the properties of operations to generate equivalent expressions

**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.

- Writing algebraic equations
- Solve algebraic equations involving addition and subtraction
- Write an algebraic equation from a real-world scenario using multiplication and division
- Write and solve an algebraic equation by determining when to use multiplication and division

**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.
