Online Educational Resource OER Title: Balancing Equations OER URL Location: http://education.ti.com/en/timathnspired/us/detail?id=18EF9D2A19F849E79D008B471CFCC028&t=A 143078BC5F44F55A1DB1F2868A94035 Core Standards addressed: Students will determine when linear equations in one variable have one solution, infinitely many solutions, or no solutions by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = bresults (where a and b are different numbers) (CCSS). Practice Standards Addressed: Students will make sense of problems and persevere in solving them (CCSS Mathematical Practice). Students will reason abstractly and quantitatively (CCSS Mathematical Practice). Grade Level: 7 Instructional Block___2___ Part __D___ Description of OER Resource: This lesson involves understanding what it means for an equation to be balanced in the process of solving linear equations with one variable. As a result, students will: Examine the graphs of the two separate expressions from a linear equation with one variable and then noticing their point of intersection as a solution to the original equation. Find the solution(s) of a linear equation by transforming it into equivalent equations in simpler forms using the idea of balancing equations and the properties of equality. Determine if a linear equation has one, infinitely many, or no solutions by examining the final equivalent equation found.
