Lesson 3.2 Simplifying Expressions

The student will be able to simplify an algebraic expression

Opening

  1. 20/25 is simplified to 4/5. Why do we simplify fractions?
  2. If I had an expression j+j, how could you write that in a simpler way? (think multiplication)

Lesson

    Combining like terms- bringing together similar parts of an expression

      2j + j + 7 + 12

      5y + 16 - y

      10r - 5 + 3 + r

      X x X + 7 - 2

      3(12y + 9)+5
