Exponent Rules and Naming Polynomials


I love teacherspayteachers. The graphic organizer from all things algebra is the bomb dot com. It was a great asset prior to playing algebra wars. I had a few errors like a missing negative sign, so that needs to be fixed prior to posting it.  I cut the foldable so the kids had their chart of squares that they need to remember on the side. If you are like my students and wonder why I skipped 14 squared, I told them I have rarely used it in higher math classes. Using this logic, I probably should have put 20 squared.


I play the video by the Ohio school of mathematical magic. Yes, that is not their name, but play one of their songs in class and BAM. Magic!  The kids are humming the tune down the hallway.


Students look like I have just taught them how to cheat when I show them how to put rational exponents in the calculator. But it gets students saying this is easy. 


I tell students that radical signs remind me of division symbols. We always divide the number "under the hat" (elementary term) by the number on the outside. This time we call it the index. The only thing I had to push hard was the square root is an exponent of 1/2. 


These types of questions pop up on the EOC every year. I see kids get overwhelmed by the equation prior to seeing that they can plug it in the calculator. Input major emphasis on these word problems. 


Colors are key to learning as visual learners. Tomorrow I will take care of my kinesthetic learners taking another example from Math = Love

Inequalities: Flipping the sign

So my kids love the interactive notebook and were pouting that I didn't have some cool new foldable for this most recent unit.  The first reason being that one step and multi-step equations are practically the same methods for solving inequalities.  But I knew that I wanted to find something awesome to drive home when to flip the inequality sign.  After searching Google for at least three days, I found it!


Changing Image Tutorial  They include images for a tutorial on how to put it together and include a template.

I am slightly afraid my children with ADHD will be lost for the rest of the day as they make the sign flip, but at the same time they should be brainwashed by the time is all said and done.

This took a bit longer than anticipated, but the kids really enjoyed the final product.
