There are two parts to this resource - the power point presentation and the notes. This is a step by step presentation on how to find the difference of squares. It explains what difference of squares is, how to identify and factor difference of squares. As the teacher you can progress though the presentation at your own pace, by clicking the slide, so that you can spend as much time on each slide as you need. While the presentation is self explaining, the notes,( which are designed to be read along with the slides), expand on the presentation. At the end of the notes are a series of worksheets from bronze through to challenge sheets. The idea being that the students would do two of the worksheets - one sheet at their level of understanding, and then the next level up to challenge them. By the end of this unit, the students should be able to identify when two terms create the conditions for difference of squares, and be able to factor them. The work sheets are designed to challenge not only the students who are just beginning to understand the concept, but also to challenge the students who find the concept easy, by having them factor out two terms from an equation to create the conditions for difference of squares.
It is always helpful to understand why you are learning a new skill, so the worksheets and the presentation show the students how being about to factor difference of squares will help them simplify their work.
