(Day 4 – The Distributive Property)


We are learning to…simplify variable
expressions by combining like terms.
                 Simplify the expression:



               We have 2 sets of… x + 3
Create a representation of the expression with Algebra
                         Tiles


          xx                 xx



         Next…Organize your simplest form:
        Write the expression in Algebra Tiles


                       2x + 6
                  Simplify the expression:



                We have 3 sets of… xy – y2 - 1
Create a representation of the expression with Algebra
                         Tiles

   xy                    xy                   xy
                                             xy
  xy       22
                        xy       22                 22
          yy                    yy                 yy




         Next…Organize your simplest form:
        Write the expression in Algebra Tiles
                              2
                  3xy - 3y - 3
                             Simplify the expression:



                          We have 4 sets of… 2x – y + x + 2y
  Create a representation of the expression with Algebra
                           Tiles

xx xx        xx           xx xx        xx           xx xx        xx           xx xx        xx
        yy        yy yy           yy        yy yy           yy        yy yy           yy        yy yy




                   Next…Organize your simplest form:
                         Remove any “Zero Pairs”
                  Write the expression in Algebra Tiles
                                            12x + 4y
Critical Thinking
o   Could we have done anything else to make
    the process easier when simplifying?
    n   Discuss with your group, write down some ideas
        and be ready to share your thoughts with the
        class.
                          Simplify the expression:



             We have 4 sets of… 3x + y
Create a representation of the expression with Algebra
                         Tiles


xx xx        xx            xx xx xx        xx xx xx        xx xx xx
        yy        yy yy               yy              yy              yy




               Next…Organize your simplest form:
                     Remove any “Zero Pairs”
              Write the expression in Algebra Tiles
                                  12x + 4y
Critical Thinking
o   Did you get the same solution?
o   Why did this happen?
    n   Discuss with your group and then write several
        complete sentences explaining how this
        happened.
                 Practice…
• Now try some practice with your team.
• Directions:
    – Read each expression carefully.
    – Use your Algebra Tiles to create a
      representation of the expression.
    – Organize your tiles as you draw your
      representation with Algebra Tiles.
    – Combine like terms in the expression and
      create zero pairs.
    – Write your simplified expression.
