# Q1W3 Algebra

Title: Teacher Carol Barnes Algebra 1 7th/8th Week 3 Aug 30-Sept 3 Unit 2 - Solving Equations
Standard(s) Taught

MAFS.912.A-REI.2.3:  Solve Linear equations and inequalities in one variable, including equations with coefficients rep represented by letters.

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.912.A-CED.1.1:  Create equations and inequalities in one variable and use them to solve problems.

Learning Targets and Learning Criteria
• solve linear equations and inequalities in one variable including equations with coefficients represented by letters.
• apply order of operations and inverse operations to solve equations.
• given a multi-step algebraic equations, 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 one variable equations or inequalities that best models the problem.
• solve equations or inequalities that model real-world problems.
