General Lesson Information
 Lesson Plan ID: 35677 Title: Equations and Solutions Overview/Annotation: This lesson will use the substitution property to determine solutions to equations and inequalities. The students will be given a replacement set of values. The student will check the values to determine if the result is true or false. The values that are true will be the solution. The student will graph the inequality solutions on the number line.This lesson results from the ALEX Resource Gap Project.
Associated Standards and Objectives
Content Standard(s):
 Mathematics MA2015 (2016) Grade: 6 16 ) Understand solving an equation or inequality as a process of answering a question: which values from a specified set, if any, make the equation or inequality true' Use substitution to determine whether a given number in a specified set makes an equation or inequality true. [6-EE5] NAEP Framework NAEP Statement:: 4NPO2c: Verify solutions or determine the reasonableness of results in meaningful contexts. NAEP Statement:: 8A4a: Solve linear equations or inequalities (e.g., ax + b = c or ax + b = cx + d or ax + b > c). NAEP Statement:: 8A4b: Interpret "=" as an equivalence between two expressions and use this interpretation to solve problems. NAEP Statement:: 8A5a: Make, validate, and justify conclusions and generalizations about linear relationships. NAEP Statement:: 8NPO2c: Verify solutions or determine the reasonableness of results in a variety of situations, including calculator and computer results.
