Title: Factoring Fanatic
This activity is designed to give students practice in "finding" the correct factors to use when attempting to factor a trinomial. The students are provided with a Tic-Tac sheet to help them discover the relationship or pattern between two numbers. Students then use their discovery to fill in a second Tic Tac sheet. At this point students have uncovered the mystery of how to locate the appropriate factors in a given trinomial. They can now factor any trinomial placed in front of them!
Title: Difference of Squares
In this lesson, from Illuminations, students explore arithmetic statements leading to a result that is the factoring pattern for the difference of two squares. Students analyze and represent patterns with symbolic rules, compare quantities with integers, and learn to communicate mathematical thinking to peers and teachers.
