 * During Session 5:**

Dear Mac Room, stop eating apples. you need to see a doctor. Love, PC Room

What do you know about working with algebraic expressions and polynomials?

I know that polynomials have two or more terms that are joined by addition or subtraction. Polynomials are a big part of the 8th grade curriculum.

=Complete the questions below during Work Time during Sessions 6-8:=

How are the second and third terms of a factorable trinomial related to the binomial factors?
 * During Session 6:**

The second term is the sum of the factors. The third term is the product of the factors. The coefficient of the second term is the sum of factors, while the constant is the product of the same factor. It can be seen in the visual representation used in GSP.

When looking at a Algebra Tile model, you can count the number of tiles that contain a variable and notice how they combine to the final sum, i.e. the second term. Also by counting the 1x1 tiles, you can see how they amount to the product of the numbers given in the original question.

Second term is the sum where the third term is the product.

How can an area model be used to determine if a polynomial can be factored?
 * During Session 7:**

Using an area model, how is factoring a polynomial with negative terms different than factoring a polynomial with all positive terms?
 * During Session 8:**
