### Cluster - Create equations that describe numbers or relationships.

by Allen Wolmer

Limit A.CED.1 and A.CED.2 to linear and exponential equations, and, in the case of exponential equations, limit to situations requiring evaluation of exponential functions at integer inputs. Limit A.CED.3 to linear equations and inequalities. Limit A.CED.4 to formulas which are linear in the variable of interest.Includes Standards A.CED.1, A.CED.2, A.CED.3, A.CED.4

### Cluster - Understand solving equations as a process of reasoning and explain the reasoning.

by Allen Wolmer

Students should focus on and master A.REI.1 for linear equations and be able to extend and apply their reasoning to other types of equations in future courses. Students will solve exponential equations with logarithms in Algebra II.Includes Standard A.REI.1

### Cluster - Solve equations and inequalities in one variable.

by Allen Wolmer

Extend earlier work with solving linear equations to solving linear inequalities in one variable and to solving literal equations that are linear in the variable being solved for. Include simple exponential equations that rely only on application of the laws of exponents, such as 5^x=125 or 2^x=1/16.Includes Standard A.REI.3
