# Access Point #: MAFS.912.A-REI.2.AP.3a

Solve linear equations in one variable, including coefficients represented by letters.
Clarifications:

#### Essential Understandings

Concrete:

• Using manipulatives represent variables.
• Identify the unknown quantity when given an equation and labeled figure.
• Use manipulatives to solve linear equations.
Representation:
• Understand formula representation (e.g., “h” in the equation means height).
• Use letters to represent numbers.
• Recognize symbols for equations and operations.
• Solve equations and one variable.
For example:
2x+4=10
x=3
General Information
Number: MAFS.912.A-REI.2.AP.3a
Category: Access Points
Cluster: Solve equations and inequalities in one variable. (Algebra 1 - Major Cluster) (Algebra 2 - Supporting Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
