# Q1W4 Algebra

Teacher Carol Barnes Algebra 7th/8th Q1W4 Unit 2: Solving Equations and Inequalities
Standard(s) Taught

MAFS.912.A-REI.1.1  Explain each step in solving a simple equation as following from the equality of numbers asserted at the previous step, starting from the assumption that the original equation has a solution.  Construct a viable argument to justify a solution method.

MAFS.9.12. A-CED.1.1  Create equations and inequalities in one variable and use them to solve problems.  Include equations arising from linear and quadratic functions, simple rational, absolute, and exponential functions.

MAFS.9.12.A-REI.2.3  Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.

Learning Targets and Learning Criteria
• apply order of operations and inverse operations to solve equations.
• given a multi-step algebraic equation, complete an algebraic proof to justify the steps of a solution and a solution method.
• identify the variables and quantities represented in a real-world problem.
• create on variable equations or inequalities that best models the problem.
• solve equations or inequalities that model real-world problems.
• solve equations using the zero product property.
