Creating real working credit card numbers using Luhn's algorithm
Great easy to follow worksheet that will keep any student engaged! Using Luhn’s algorithm you can visually see how to apply this to check the validity of credit card numbers. I set up the table so that students can input a 16 digit number and follow the simple process to check if their number works. I start with a worked example and then I have two sides of blanks for students to use. This is a great lesson for Xmas, Easter or Summer break last lesson if you are looking for a lesson that will ma

Solving for the nth Term in Quadratics Using a Chart Technique
This is a way for student to find the nth term of a quadratic using a systematic algorithm that they usually find (not only) less complicated than guess and check, but also fun. Many feel that it feels like they are solving a puzzle. They find first and second differences through a chart they fill in, and then create a second chart to use their findings and actually formulate the nth term statement.

Cosmo's Minus Method (Poster / Handout)
Cosmo's Minus Method is an adaptation of Cramer's Rule I made for my Algebra 2 class. I wanted them to have this algorithm as an alternative to substitution or elimination to solve moderately difficult systems of 2 linear equations in standard form. I chose not to call it Cramer's Rule because a quick google search would reveal how to use Cramer's Rule with the available TI-84 Graphing Calculators. Also, the title of the algorithm "Cosmo's Minus Method" comes from the name of the crazy neighbor

Encryption Competition
After learning about basic encryption techniques, students will engage in a two-part team competition, in which they will design their own encryption algorithm in the first part, and in the second, they will race to figure out the other teams’ algorithm(s) before theirs gets cracked. Best suited for a 8th or 9th grade classroom, this lesson/game can serve as a study of functions, as this notation is what will be used for the algorithms. Since the goal isn’t to decrypt, but rather to figure out w

Understanding Absolute Value Expressions
My students really struggled once we got into the section on Absolute Value and Algebraic Expressions. I needed a way of teaching them the concept conceptually, not just the standard algorithm way. I created this Powerpoint to use in class to get them past the "process" and to get them to the conceptual understanding of absolute value in the form of x-b=c.

Factoring Lesson 4: Factoring trinomials when a = 1 (AC Method)
Factoring trinomials whose leading coefficient (a) is 1. Notes included.
I do not teach the "guess and check" method of factoring; students struggle with it because there is no process. The "AC method" uses a process/algorithm to easily factor a trinomial; it relies on the concept of factoring by grouping.
1. Multiply a and c
2. Find factors of "ac" that add up to "b"
3. Rewrite "bx" using the factors you found
4. Factor by grouping
Because of this method, the only "new" thing between thi

Lesson 11: Rationalizing the Irrational
Students use the concept of a perfect square to compute the square root of a number that is a non-perfect square. They use this to develop the concept of an irrational number. They then reflect upon their process to develop an algorithm to more precisely estimate square roots.
