  1. Solving Equations Using Manipulatives Two Color Counters

  2. Spiraling

  3. State Standards

  4. Solve the equations using the Cup Method. Record your actions algebraically.

  5. 1. 2x + 5 = 72. 3x – 5 = 83. x + 7 = 14. 2x + 3 = 115. 3x +7 = 136. 3x – 1 = 5

  6. Guiding Questions What is a variable? What object is representing the variable in the equation? What color represents a positive number? What color represents a negative number? What does equality mean when you are solving equations? What operation will get undone first? How could you add into the equation to isolate the variable? What do you understand about the problem? How are the actions recorded with the Cup Method related to the actions recorded with the symbolic method of solving?
