7AF.1.1 Use variables and appropriate operations to write an expression, an equation, an inequality, or a system of equations or inequalities that represents a verbal description (e.g., three less than a number, half as large as area A).

7AF.1.2 Use the correct order of operations to evaluate algebraic expressions such as 3(2x + 5)^2.

C_K
7AF.1.3 Simplify numerical expressions by applying properties of rational numbers (e.g., identity, inverse, distributive, associative, commutative) and justify the process used.

7AF.1.4 Use algebraic terminology (e.g., variable, equation, term, coefficient, inequality, expression, constant) correctly.

7AF.2.0 Students interpret and evaluate expressions involving integer powers and simple roots:  
7AF.2.1 Interpret positive whole-number powers as repeated multiplication and negative whole-number powers as repeated division or multiplication by the multiplicative inverse. Simplify and evaluate expressions that include exponents.
   
 
     
Ready
7AF.2.2 Multiply and divide monomials; extend the process of taking powers and extracting roots to monomials when the latter results in a monomial with an integer exponent.
     
 

Ready
C_K, R_F
7AF.3.0 Students graph and interpret linear and some nonlinear functions:  
7AF.3.1 Graph functions of the form y = n^2 and y = n^3 and use in solving problems.
    
Ready
7AF.3.2 Plot the values from the volumes of three-dimensional shapes for various values of the edge lengths (e.g., cubes with varying edge lengths or a triangle prism with a fixed height and an equilateral triangle base of varying lengths).
       
 

    
Ready
7AF.3.3 Graph linear functions, noting that the vertical change (change in y- value) per unit of horizontal change (change in x- value) is always the same and know that the ratio ("rise over run") is called the slope of a graph.
       
 
 Ready
7AF.3.4 Plot the values of quantities whose ratios are always the same (e.g., cost to the number of an item, feet to inches, circumference to diameter of a circle). Fit a line to the plot and understand that the slope of the line equals the quantities.
       
 
Ready
7AF.4.0 Students solve simple linear equations and inequalities over the rational numbers:  
7AF.4.1 Solve two-step linear equations and inequalities in one variable over the rational numbers, interpret the solution or solutions in the context from which they arose, and verify the reasonableness of the results.
       
 


Ready
7AF.4.2 Solve multistep problems involving rate, average speed, distance, and time or a direct variation.

After solving problems paste this into VT column:

x available
y needed

Then center these.
