|Big Idea/Theme: Solving Equations and Inequalities |
| |
|Understandings: |
|Linear Equations and Inequalities |
|Compound Inequalities |
|Absolute Value Equations and Inequalities |
|Literal Equations/Formulas |
|Essential Questions: |Curriculum Goals/Objectives |
|How do we justify the number of solutions to an equation? |N-Q.1 Use units as a way to understand problems and to guide the solution of multi-step problems; |
| |choose and interpret units consistently in formulas; choose and interpret the scale and the origin in |
| |graphs and data displays. |
| |N-Q.2 Define appropriate quantities for the purpose of descriptive modeling. |
| |N-Q.3 Choose a level of accuracy appropriate to limitations on measurement when reporting quantities. |
| |A-SSE.1 Interpret expressions that represent a quantity in terms of its context. |
| |a. Interpret parts of an expression, such as terms, factors, and coefficients. |
| |A-CED.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 functions. |
| |Note: At this level, focus on linear and exponential functions. |
| |A-CED.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. |
| |A-REI.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. |
| |A-REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients |
| |represented by letters. |
