Chapter 2: Solving one-step equations and inequalitiesStage 1 – Desired ResultsAERO.7.NS.1d-Apply properties of operations as strategies to add andsubtract 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 ofanswering a question. Use substitution to determine whether a given numberin 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 usethem to solve problems.AERO7.EE.4- Use variables to represent quantities in a real-world ormathematical problem, and construct simple equations and inequalities tosolve problems by reasoning about the quantities.Enduring Understanding:Students will understand thatEven though with thevariables, the expressionsare still following the sameproperties as a numericalexpression.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 aninequality?How can we make calculateeasier?Knowledge:Students will knowThe properties of additionand multiplication and howto use them.The distributive PropertyDifferent types of equationsand how to check theSkills:Students will be able toUse the DistributiveProperty.Write and solve equations.Write, solve, and graphinequalities.
