O.U.S.D/TASEL-MMulti-step Equations

• Teachers Assisting Students to Excel in Learning
  Mathematics
• Special thanks to all the COACHES and Colleagues
  and especially, Dr. David Pagni, Dr. Dianne
  DeMille Dr. David Cash

Students will be able to solve 2-step linear
equations in one variable over the rational
numbers., interpret the solution, and verify the
reasonableness of the results.(AF 4.1)
Rational Students will practice problem-solving
skills necessary for higher level math As related
to multi-step equations.
Example 2X 6 26 Step 1 Subtract 6 from both
sides 2X 6 626-6 Simplifying we
see 2X 20 Step 2 Divide each
side by 2 2X 20
2 2 Simplifying we see
X 10
Substituting 10 in for X we see
2(10) 6 26 Multiplying we see
20 6 26 Summing up we get
26 26
CORRECT !!!

Solving Multi-step Equations (45 or 90 minute
lesson plan) Objective Students will be able to
solve multi-step equations, and check work. Part
I. Pre-quiz, or Warm-up, or HW check Example
Pre-quiz
1. 2. 3. 4.

• Part II. Review Vocabulary and Concepts (Cornell
  Notes)
• Properties of Equality
• Do/Undo Concept
• Part III. Example Problems in Notes or on
  Individual Whiteboards
• For 45 minute lessonClosure could be inserted
  here.
• Additional activity for 90 minute period or
  second day of lesson
• Part IV. Poster Walk
• Guidelines for Activity
• Students work in groups of 4
• Each person has a different color marker
• Two members solve problems and two members check
  work.
• Teacher posts problems on posters around room.
  Groups solve problems on their poster before
  writing a new problem for the next group to
  solve.
• Part V. Closure
• Students solve 3 sample problems individually.
• Choose one of the problems from above, and write
  a summary of the steps necessary to solve it.
• Students can then share this summary with their
  partner, or with the entire class.
