Interactive Notebooks
I've been bitten!!! And the kids love these books. And yes, I teach high school. High school Seniors to be exact. We have several new, awesome, teachers at our school this year. A few of them are using Interactive Notebooks. I had never heard of them before. I'm always looking for something new so I immediately started researching this idea.
I did not come up with these ideas myself. The "numbers important to me", the cover, the spine, and the rubber band, all come from ideas I saw on Pinterest.
Right now we are working on Family of Functions, so far we have just been studying quadratics. We spend several days learning all the ways to transform a parabola. Next week we will take what we have learned and apply it to cubics, absolute value, hyperbolas, circles, square roots, linear, etc.
We started by gathering data. I gave them a sheet of paper with 8 concentric circles. They cut out the largest circle and weighed it. They continued cutting circles and weighing them. Then the book walked them through several questions. They entered their data into a calculator and then typed y = ax^2 into the calculator and used guess-n-check to find a.
After spending some time learning what a, h, and k transform a graph, they did a few practice problems.
We created a foldable to review the three forms of quadratic equations.
We changed standard form to vertex form. This book calls is graphing form. When we have equations in graphing form I will not let them use a calculator to graph. And a graph has a minimum of 5 ordered pairs on the coordinate graph. The left side shows averaging the x-intercept to find the h value and then the k value. The right side show completing the square. We first used Algebra Tiles and then moved to algebra.
Here is a foldable that I used to review factoring.
