SWBATsolve two-step equations
Mon, 11/4/10

• Agenda
• Solving equations on poster board (15 min)
• Gallery walk (30 min)
• Warm-Up.
• 1.) On your poster, solve your equation. Show
  all work (but you already knew that!)
• Write out the steps as you solve the problem
• CHECK your answer
• HW3-Solving Algebraic Equations Two Step
  (solve and check each equation)

Gallery Walk Instructions

• The person in your group whose birthday is
  closest to todays date (November 1) will first
  stay with your poster to explain how you solved
  the equation
• The other person will be rotating to the
  different stations with your hw3
• When I say rotate (after 3-4 minutes) you will
  rotate clockwise to the next poster
• After 3 rotations, you and your partner will
  switch
