Special Right Triangles: Proving/Practice BUNDLE w/BONUS Poster!
Help your geometry students understand the “why” behind the algorithms for special right triangles with this 7-page investigation and guided notes activity. Your students will use the Pythagorean Theorem and the properties of isosceles and equilateral triangles to discover how to solve for any side of a 45-45-90 and 30-60-90 triangle. Clear diagrams and step-by-step algebraic proofs allow students to develop the foundational understanding for working with these common right triangles, ensuring a

QVIII - Getting Ready for Completing the Square
Completing the Square (CTS) doesn’t have to be a memorized algorithm. This worksheet gives students a chance to put together the puzzle pieces that are needed to figure out "what goes where" when doing CTS. First they square some binomials, then use those patterns for fill-in-the-blanks equations. Finally, they have problems to encourage them to think about the role of parentheses in CTS. This is ready to print, or to assign as an online Easel Activity. The digital version is ready-to-use, but y

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.

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.

Patterns and sequences
Patterns and sequences are the language of prediction, allowing students to see the underlying order in data and forecast future events. This skill is used by scientists to track population growth, by economists to predict market trends, and by computer programmers to create loops and algorithms.
