Mathematics Department – Algebra 1

Unit 4 - SYSTEMS OF EQUALITIES/INEQUALITIES
Enduring Understanding: Knowing how to apply different methods of solving systems of equations/inequalities enables one to develop steps to become a life-long problem solver.
Essential Questions: When is it beneficial to use one type of method over another when solving systems of equations? What does having no solution to a problem mean?
Target Goals: Solve a system of equality using graphing, substitution, and elimination with or without technology. Solve a system of inequality in two variables with or without technology. Solve and graph compound inequalities on a number line.	Assessment: Quizzes Tests Open Ended Questions Checks for Understanding
Activities: Four people group – given an equation, each person solves using a different method (graph with calculator, graph without calculator, substitution, and elimination). The group will discuss and compare the different methods used and decide which is best for the given equation. Supplemental Material – Pizzazz worksheet!
State Goals: 8.D.4 - Formulate and solve linear and quadratic equations and linear inequalities algebraically and investigate nonlinear inequalities using graphs, tables, calculators and computers. 8.B.4b - Use the basic functions of absolute value, square root, linear, quadratic and step to describe numerical relationships.
