Key Facts to Know in Algebra 1

The main focus (a.k.a. target) for the year in an Algebra 1 course is the STAR Test.

Mr. L wants all students to achieve at their highest level, and to do that requires commitment, dedication, time, and perseverance. Success on the STAR Test does not happen by magic, but rather by knowing key facts, techniques, and algorithms. Here are items Mr. L wants you to know for success in Algebra 1:

Statement of the Quadratic Formula

Proof of the Quadratic Formula

Six ways to write the direction of a straight line

Four ways to write the equation of a straight line; you need to know the equation as well as the name of the equation

Solution of a system of two linear equations

By substitution

By linear combination

By determinants

Solution of absolute value equations and inequalities

    I am a new high school math teacher. I teach Alg. 1, 1A, and 1B. to slow and difficult students.
    I am looking for answers on how I can address my classes and get them motivated, lean Algebra 1, and be respectful at the same time.
    Since these are low achiever, what can I do to make things more interesting and have them engage in the learning process without disrespect.

    Hi Bryan,
    If you visit my companion website, http://www.tttpress.com, you will find several free activities that you can download. You can also download many handouts from conferences. This will give you a taste of the types of things that thousands of other teachers have used in their classrooms with success. Best wishes,

    Do you think Algebra restart classes for failing students is a good idea?

    Hi Leslie,
    I think many students may need “a fresh start” with another teacher and another approach. Students can flounder when only given a symbolic approach to algebra, but may succeed when offered a more conceptual approach with less symbolic manipulation and cumbersome arithmetic. An approach that can be successful is to show “Algebra in the Real World”, so that students can see how math relates to things around them.
    Best wishes,
    - Mr. L
