Algebra 2H 4.09 Matrix Algebra Day 1 Spring 2017 (Editable)
This worksheet is designed to help students with the topic of matrix algebra, including an algorithm for multiplying matrices visually, the identity matrix, and how we use the concept of an inverse matrix instead of "division" of matrices.
I start out class with several examples of what today's lesson will be about. Once we finish doing the notes together, I have them get to work within their groups on this worksheet.
I use this activity within cooperative groups, and I circulate to make sure

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.

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

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

In this organizer, multiple representations of linear functions are displayed in a succinct and connected way. I use this document to help students "frame in" the learning goals, summarize lessons, create a useful reference, and develop sense of function by repeatedly focusing on all four faces(tables, graphs, equations, and situations.) I also find this document useful for planning.
