- 1. Monday, November 4th 2013 Objective: SWBAT solve two step equations using inverse operations. Agenda: Do-Now Group Challenge Number Riddles Guided Notes & Partner Practice Partner Activity: Equation Sorting Exit Card
- 2. True or False? 10 - x = -9 x = -1
- 3. True or False? x + 4 = -6 + 4 + 4
- 4. True or False? 3x = -6 -3 -3 x = -9
- 5. Group Challenge Ten times a number plus four is equal to 24. What number am I?
- 6. Think: Why can’t you subtract 2/3 from both sides? You can’t subtract 2/3 from both sides because ________________________ ____________________. 2 3 x + 4 =10
- 7. Think: Why can’t you add 5 to both sides? You can’t add 5 to both sides because ________________________ ____________________. w 5 -12 = 3
- 8. Think: Why can’t you subtract 2 from both sides? You can’t subtract 2 from both sides because ________________________ ____________________. 2x+8=10
- 9. Think: Why can’t you add 5 to both sides? You can’t add 5 to both sides because ________________________ ____________________. 6-5x = 51
- 10. Partner Practice 1) Complete a – d. Work independently. Show your work in column 1. 2) Write your final answer in column two. 3) Fold your paper along the dashed line. 4) Find a partner. Then, place your folded papers next to each other so that your column 3 and their column three are beside each other. 5) If your answers are the same, place a check mark in box three. If your answers are different, Write a sentence describing the error in column four, then solve the problem together. 6) Continue working, stopping to check in with your partner after your have each completed four problems.
