Ohio Mathematics Academic Content Standards (2001)
Patterns, Functions and Algebra Standard
Analyze functional relationships, and explain how a change in one quantity results in a change in the other.
Use algebraic representations, such as tables, graphs, expressions, functions and inequalities, to model and solve problem situations.
Grade Level Indicators (Grade 5)
Describe how the quantitative change in a variable affects the value of a related variable; e.g., describe how the rate of growth varies over time, based upon data in a table or graph.
Grade Level Indicators (Grade 6)
Identify and describe situations with constant or varying rates of change, and compare them.
Grade Level Indicators (Grade 7)
Analyze linear and simple nonlinear relationships to explain how a change in one variable results in the change of another.
Grade Level Indicators (Grade 8)
Use symbolic algebra (equations and inequalities), graphs and tables to represent situations and solve problems.
Grade Level Indicators (Grade 9)
Describe problem situations (linear, quadratic and exponential) by using tabular, graphical and symbolic representations.
Grade Level Indicators (Grade 10)
Solve real-world problems that can be modeled using linear, quadratic, exponential or square root functions.
Principles and Standards for School Mathematics
Use mathematical models to represent and understand quantitative relationships
model and solve contextualized problems using various representations, such as graphs, tables, and equations.
draw reasonable conclusions about a situation being modeled.
