                     Day 3. C7.7 Multiplying Polynomials: Page 492
                     The teacher will review the distributive method (FOIL) and then show how the box method can
                     be used in the general case for a poly times a poly. Algebra tiles may be used the reinforce
                     instruction.

                          Also teach the Box Method which will be the preferred method:
                                        X   +2

                                    X2        2X             Multiply rows times the columns.
