Checks for Understanding (Formative/Summative Assessment)
Basic Operations - Perform basic operations on algebraic expressions (including grouping, order of operations, exponents, square/cube roots, simplifying and expanding).
0806.3.2 Equations and Inequalities - Represent algebraic relationships with equations and inequalities. 0806.3.3 Linear Equations - Solve systems of linear equations in two variables and relate the systems to pairs of lines that intersect, are parallel, or are the same line. 0806.3.4 Linear Inequality - Understand the relationship between the graph of a linear inequality and its solutions. 0806.3.5 Two Variables - Solve linear inequalities in two variables (including those whose solutions require multiplication or division by a negative number). 0806.3.6 Slope - Identify x- and y-intercepts and slope of linear equations from an equation, graph or table. 0806.3.7 Rate of Change - Analyze situations and solve problems involving constant rate of change. 0806.3.8 Proportion - Recognize a proportion as a special case of a linear equation and understand that the constant of proportionality is the slope, and the resulting graph is a line through the origin. 0806.3.9 Function Rule - Given a function rule, create tables of values for x and y, and plot graphs of nonlinear functions. 0806.3.10 Nonlinear - Distinguish quadratic and exponential functions as nonlinear using a graph and/or a table of values. 0806.3.11 Distinguish Functions - Distinguish between the equations of linear, quadratic, and exponential functions (e.g. function families such as y=x , y=2 , and y=2x). 0806.3.12 Contrast Rate of Change - Understand how rates of change of nonlinear functions contrast with constant rates of change of linear functions. 0806.3.13 Symbolic Algebra - Represent situations and solve real-world problems using symbolic algebra.
