Chapter 2: Solving one-step equations and inequalities Stage 1 – Desired Results AERO.7.NS.1d-Apply properties of operations as strategies to add and subtract rational numbers. AERO.8.EE.7b-Using the distributive property and collecting like terms. AERO.6.EE.5 Understand solving an equation or inequality as process of answering a question. Use substitution to determine whether a given number in a specified set makes an equation or inequality true. AERO.8.EE.7-Solve linear equations in one variable. AERO.HSA.CED.1-Create equations and inequalities in one variable and use them to solve problems. AERO7.EE.4- Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. Enduring Understanding: Students will understand that Even though with the variables, the expressions are still following the same properties as a numerical expression. Essential Questions: What does “x” mean?What is the difference of aninequality and an equation?Why we graph an inequalitybut not an equation? How many solutions in an inequality?How can we make calculateeasier? Knowledge: Students will know The properties of addition and multiplication and how to use them. The distributive Property Different types of equations and how to check the Skills: Students will be able to Use the Distributive Property. Write and solve equations. Write, solve, and graph inequalities.
answers. How to use the four different operations to solve one-step equation and inequality. Use numbers properties to do mental math. Stage 2- Assessment Evidence Performance Tasks: Other Evidence: Worksheets and Assignments Quizzes Chapter test Stage 3 – Learning Plan Day1 #2 Lesson Plan iSC Standards AERO.7.NS.1d Procedures Homework Due: Practice 2-1 Introduction to the Unit(class note): Pass out classnotes Explain the Chapter 2 schedule, learning path, quiz and test dates. Whole Class Instruction(ppt 1-1, class note): Explain learning goal for 2-1 Commutative properties Associative properties Identity properties o Teacher will use algebraic expression and ask students write numerable expression to help understand. Whole Class activities: Use properties to do mental math.
