Product Description
These equations have no "b term" and do not use completing the square.

Included in this zip folder are 8 SMART Notebook files. 1 is an introductory lesson and 7 are assignments. A brief description of each:

The introduction is a 49 slide SMART presentation. It introduces the learner to:
1. The principle square root
2. The definition of +-
3. What is "the square"?
4. How to isolate "the square"
5. How to make 2 degree 1 equations out of the degree 2 equation

Assignment C is a 24 question multiple choice and short answer assignment. The student is asked to identify the square, find the principle square root, identify an answer in +- notation and how to isolate the square. It is on 1 page for easy printing and coded for SMART Response.

Assignment D is a 24 question multiple choice and short answer assignment. The student is asked to identify the principle square root, solve an equation with a +-, isolate and identify the square. It is on 1 page for easy printing and coded for SMART Response.

Assignment #3 is a written assignment. The student is given 8 quadratic equations and must solve them by extracting roots. It is on 1 page for easy printing.

Proof Assignment # 2 is a 12 question multiple choice assignment. The student is given an equation in the 2 column proof format and asked to identify the 1 missing reason. It is on 1 page for easy printing and coded for SMART Response.

Proof Assignment #3 is like #2

Proof Assignment #5 is a 12 question multiple choice assignment. The student is given a proof in the 2 column format. All the reasons are missing. The student identifies the on that is highlighted. It is on 1 page for easy printing and coded for SMART Response.

Proof Assignment #6 is like #5

The reasons used in the proofs are:

1. Subtraction property of equality
3. Division property of equality
4. Symmetric property
5. Simplify by like terms
6. Distributive property
7. Extracting roots
8. Definition of +-
