Algebra 2 (& GT)
Overarching Standards
Instructional Note: The following standards should be emphasized throughout all units of instruction. These standards should not be taught in isolation.
What will my child learn?
Students will:
Reason quantitatively and use units to solve problems.
N.Q.A.2
Define appropriate quantities for the purpose of descriptive modeling.
Interpret the structure of expressions.
A.SSE.A.2
Use the structure of an expression to identify ways to rewrite it.
Create equations that describe numbers or relationships.
A.CED.A.1
Create equations and inequalities in one variable and use them to solve problems.
Interpret functions that arise in applications in terms of a context.
F.IF.B.5
Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of personhours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.*
F.IF.B.6
Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.
Summarize, represent, and interpret data on quantitative variables.
S.ID.B.6
Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
a. Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear and exponential models.
b. Informally assess the fit of a linear function by plotting and analyzing residuals.
c. Fit a linear function for a scatter plot that suggests a linear association.
Students will:
