Unit 2: Equations & Inequalities in One Variable
20 days
Insert unit priority standards(s) below (include numerical and letter codes). Underline the skills (verbs)
students must master and circle the concepts (nouns) that students need to know.
1) A-CED.A.1- Create equations and inequalities in one variable and use them to solve problems. Include
equations arising from linear and quadratic functions, and simple rational and exponential function.
2) A-CED.A.3: Represent constraints by equations or inequalities, and by systems of equations and/or inequalities,
and interpret solutions as viable or non-viable options in a modeling context. For example, represent inequalities
describing nutritional and cost constraints on combinations of different foods.
3) A-CED.A.4: Rearrange formulas to highlight a quantity of interest, using the same reasoning as in
solving
equations. For example, rearrange Ohm’s law V = IR to highlight resistance R.
4) A-REI.A.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.

Formative Assessment Lessons.
Sorting Equations and Identities
The teacher leaders for the Gates grant work recommend that Warren County Administration adopt the
practice that Warren County Math teachers do a minimum of one Formative Assessment Lesson per
quarter. Choices for formative assessment lessons may be found at
