Lesson Excerpt:

II. Special Products

- "Today's lesson is going to focus on some special types of problems. In these problems, you will still be multiplying binomials, and trinomials, but the work will be a little different."
- "Before we look at an example, what does it mean to square something?"
- Student answer- squaring means that you multiply the number by itself.
- "Okay good, so when I am going to square a number, I use the exponent 2 and that means that I am going to multiply that number by itself. In fact any term with an exponent, the exponent tells you how many times to multiply the term by itself. Exponents are a shortcut for multiplication."
- "Are there any questions on that?"
- Wait a few minutes for student questions and then move on.
- "Keep all of this in mind, and here is an example of a special type of problem."
