  2. Hands-On Equations Is Algebra For Middle School Students

  3. Level IILesson #8 through #16 Solve Such Equations As: 2x + (-x) + 3 = 2(-x) + 15 And 2x – 3(-x) = 20 + x

  4. Lesson 8White pawn is called “star” and is written as “x” 2(3x + 1) = 2x + 10 1 1 8 10 X = 2 Remember when doing a check you put the answer back in the original problem, not the solved problem. 2 2 2 2 2 2 2 2 1 1 10 14 = 14

  5. Lesson 9Since x and x are Opposites If x = 2, evaluate: 2x + x + x + x +5 0 The expression is worth 7 5

  6. Lesson 10Legal Move Making O 3x + x = x + 4 Practice: 2x + x + x = x + 5 4 X = 4, X = -4 Check 8 = 8 X = 5, X = -5 Check 10 = 10

  7. Lesson 11 You can add pawns to the Equation 2x = x + 6 Practice: 3x = x + 4 X = 2, X = -2 check 4 = 4 6 X = 1, X = -1 check 3 = 3

  8. Lesson 12 Zero My Hero 2x = x + 6 Practice: x + 2x + 4 = x X = 2, X = -2 check 4 = 4 6 X = -1, X = 1 check 1 = 1

  9. Lesson 13Putting it all Together 2x + x + 3 = 2x + 15 Practice: 3x + x + 5 = x + 12 7 3 8 5 X = 4, X = -4 Check 7 = 7 7 2 5 10 X = 7, X = -7 Check 19 = 19

  10. Lesson 14Adding a Zero When Needed 2x – x = 12 10 2 X = 4, X = -4 Check 12 = 12 Practice: x – 3x + 2 = 8 – 2x X = 1, X = -1 Check 17 = 17 2 8 6

  11. Lesson 15Recognizing a written “(-x)” as x 2x + (-x) + 3 = 2(-x) + 15 3 10 5 2 X = 4, -X = -4 Check 7 = 7 Practice: 2x - (-x) + 4 = 2(-x) + x 4 X = -1, -X = 1 Check 1 = 1

  12. Lesson 16Pictorial Notation • Students transfer their hands-on learning with the game pieces to a pictorial notation using paper and pencil. 2x = x + 6 x x x X = 2, X = -2 Check 4 = 4 x x 6 2x + x + 3 = 2x + 15 X = 4, X = -4 Check 7 = 7 x x x x 12 3 15 x x x x x
