Solving Systems of Equations
6 lessons, about 14 days with the quiz, review and test, in one download: Systems of Equations by Graphing, Systems by Inspection, Systems of Equations by Substitution, Systems of Equations by Elimination, Systems of Equations Word Problems, Comparing Two Plans.
6 lessons, in teaching order
Built to 8.EE.C.8a, 8.EE.C.8b, 8.EE.C.8c. Each lesson has guided notes, practice, an exit ticket, a homework page, worked answer keys and a click-by-click Teacher Deck.
- Lesson 1 Systems of Equations by Graphing I can graph two linear equations, read where the lines cross as the solution, check it in both equations, and tell from the slopes when there is no solution or infinitely many.
- Lesson 2 Systems by Inspection I can tell whether a system has one solution, no solution or infinitely many by comparing its equations, slopes and y-intercepts.
- Lesson 3 Systems of Equations by Substitution I can put the expression for one variable into the other equation, solve, back-substitute for the second variable, and check the ordered pair in both equations.
- Lesson 4 Systems of Equations by Elimination I can add or subtract two equations so one variable cancels, multiply one or both equations first when needed, and check the ordered pair in both equations.
- Lesson 5 Systems of Equations Word Problems I can define both variables with units, write one equation for each fact in the story, solve with substitution or elimination, check the values in the story, and answer in a sentence.
- Lesson 6 Comparing Two Plans I can write each plan as a fee plus a rate, find the count where the plans cost the same, and say which plan costs less on each side of it.
