 Patterns, Functions, and Algebra Focus: Linear Equations The student will a)   solve one- and two-step linear equations in one variable; and b)   solve practical problems requiring the solution of one- and two-step linear equations. HCPS Course 2 Curriculum Guide
 Essential Knowledge and Skills Represent and demonstrate steps for solving one- and two-step equations in one variable using concrete materials, pictorial representations and algebraic sentences. Solve one- and two-step linear equations in one variable. Solve practical problems that require the solution of a one- or two-step linear equation. Essential Understandings When solving an equation, why is it important to perform identical operations on each side of the equal sign? An operation that is performed on one side of an equation must be performed on the other side to maintain equality.

1. Modeling One-Step Equations - Activity A: Solve one‑step equations using an area model. Drag tiles into two bins, each representing a side of the equation, and isolate an x‑tile on one side.
2. Modeling and Solving Two-Step Equations: Solve a two‑step equation using a cup‑and‑counter model. Use step‑by‑step feedback to diagnose and correct incorrect steps.
3. Road Trip (Problem Solving): Plan a cross-country road trip through various U.S. state capitals. First choose a vehicle to drive, and then fill up the tank with gas and go! Find the range and gas mileage of each vehicle, and discover the shortest path between two cities.
4. Solving Equations By Graphing Each Side: Solve an equation by graphing each side and finding the intersection of the lines. Vary the coefficients in the equation and explore how the graph changes in response.
5. Solving Two-Step Equations: Choose the correct steps to solve a two-step equation. Use the feedback to diagnose incorrect steps.
