Introducing Quadratic Factoring with Conspiracy Theory in Special Ed Algebra 2
Properties of logarithms can be tricky for students in Algebra 2 and teachers. I love using activities to teach logs and this post explains how I teach them to my kids!

These simple horizontal and vertical posters are a cute addition to ANY classroom. Wrap them around the corner of your whiteboard or bulletin board and they hardly take up any space at all. These posters will help your students remember the difference between horizontal and vertical.This is a black...
Are your Algebra 2 students struggling with the steps to sketch polynomials? In this post are links to activities I use in my Algebra 2 class to teaching and practice sketching polynomials. Also includes links to a few free pdf printables that work well in an Algebra 2 class.

Students at our school can opt out of second semester final exams by doing well on state assessments. Most of my students fall into that category. Given the choice to take finals or get out of school two days early, you can imagine what most high school students will choose. With no exams, trying to convince students to review at the end of the year is next to impossible. A few years ago, I switched to a final project instead: Create a picture using parent functions (and/or conics) and their transformations along with restricted domains or ranges. I like how it encompasses so many things we have learned this year. Review, without looking at all like a painful study guide. Leading up to this project, I do a week-long mini-unit reviewing all the different types of graphs we've studied this year -- linear, absolute value, quadratic, exponential, rational, polynomial, and conics. We work on their transformations, and then add in restricted domains and ranges. We sketch simple piecewise functions using known functions, and then more complex ones using a graphing calculator. At the end of the unit, they do this outline of Texas using a graphing calculator. (I wish I knew where this came from. Someone gave it to me and it became the inspiration for this project). Now students are primed to make their own picture. Here are the project requirements, rubric, and final product sheet. Some questions/discussions that come naturally out of this activity: How do I make the vertex of x^2 hit the point (5, 2)? How do I make x^2 skinnier? How to I find where this straight line intersects this parabola? How do I restrict this domain/range to get half of the ellipse? And (yikes!) how do I write the equation for this straight line? Here are a few student samples from a previous year. I loved the penguin! I've received a few projects already this year that are okay. Students are looking for ways to keep it as simple as possible and still meet all the requirements. I am not disappointed, really. They are doing exactly what I have asked them to do. For next time, I think I will edit the project a bit to require that more variety in graph selection be used. Over all, it isn't a bad way to end the year. I like that students are still working on math up to the last day. They are being creative and I hear mathy conversations taking place. And I am not pulling my hair out trying to convince anybody to review for an exam they aren't going to take.
This has been my favorite project for two years now! I have reserved the computer lab for an entire week each time and let the students show...

There are many different versions of the Angry Birds Parabola Project. We compiled the best methods to use with your class. Transforming Parabolas.
Multiplying Binomials #1 is the first worksheet in the series. This worksheet practices on multiplying binomials with a leading coefficient of 1 and only positive terms. It is best suited for middle school or Algebra Intervention. Worksheet #1: LC of 1 and positive terms. Worksheet #2: LC of 1 and positive/negative terms. Worksheet #3: LC greater than 1 and positive terms. Worksheet #4: LC greater than 1 and positive/negative terms. Worksheet #5: Positive/Negative LC greater than 1 and positive/negative terms. Each question corresponds to a matching answer that gets colored in to form a symmetrical design. Not only does this make it fun and rewarding for students but it also makes it easy for students and teachers to know if the worksheet has been completed correctly. Great for classwork, homework, additional practice, extra credit, and subs. The designs can also be cut out and quilted together to make a great art piece. The pdf file contains the worksheet and a key. Please download the preview file to see exactly what you will get. This is the same worksheet as factoring binomials with a leading coefficient greater than 1 as far as the problems and coloring patterns.

Another quick tip. This time how to multiply matrices. Begin with the matrix multiplication problem: Then move the first matrix down. [Note: Since matrix multiplication is not commutative, this is important. Although it should be noted that the same effect can be accomplished by moving the second matrix up. But under no circumstances should the reverse be tried.] The answer will go in the new space you have created in the bottom right corner. Immediately you can see (if the product is possible) the shape of the answer. In this example it is a 2x2 matrix. Pick a position in the answer matrix and follow across from the left and vertically from above to figure out which numbers you will use. Multiply pairs beginning with the outermost numbers (the blue 1 and 7 in the example) and sum with the product of the next pair in until you run out of pairs. The answer will go in the position where the arrows meet. Remember not to use numbers from your answer when computing other spaces. For example, the 58 was not used to find the 64 below. Continue with each position until the answer matrix is complete! But what if the matrices in question are not able to be multiplied? Consider the following case. Although it initially looks like our answer will be a 2x2 matrix, we see that the 3 does not have a pair, so these matrices cannot be multiplied in this order.
My Algebra 2 students needed more practice with graphing and writing the equations of quadratics in vertex form so I made this set of task cards. You can download them free from this link.
