MATH-O

MATH-O!  That saying filled my classroom the other day.  It was awesome.

In my GPS Advanced Algebra class, we have been talking about Polynomial functions.  For this lesson, they had just learned transformations of a polynomial from its parent function the day before.  This activity was used as a review

I hate worksheets, and I avoid them when I can, so I came up with MATH-O.
MATH-O is like bingo...but better...because it has math.

Because I don't feel like filling in 50 different MATH-O boards for the students to use, I let them fill in their own.  I give them a blank board and the answers to the questions I will ask.  They can arrange them any way they like.  This also gets them practicing proper notation.

The board that I used is below.  Feel free to use it yourself!

MATH-O with Polynomial Transformations

The first page is the blank MATH-O board.
The second page has the answers that the students put into their board (one per box!!).
**I put both pages side-by-side on a single sheet for ease.
The third and fourth pages are the keys for calling out the problems.  You can either cut them into strips and pull them randomly, or you can choose them randomly (keep track with a highlighter or pen).  The questions to read to the students are on the right side.  The answers (the ones on their boards) are on the left side of the page.  You can use your key to check when I student gets MATH-O.

Don't stop with boring, straight across MATH-O.  Do the "X", the "Border", or the "Blackout".  The students don't think they are doing any math in class (which they TOTALLY are), and they are eager for more problems.  What teacher doesn't want that???

**Have a small prize for the students that get MATH-O.  The extrinsic motivation is very powerful.  Extra points also work.

Happy Transforming!

End Behavior of Polynomials - "Pharaoh Dance"

So I was teaching my students about end behavior of polynomial functions, and I realized I needed something other than a pretty chart to help them remember the different options for the end behavior (they still got the chart just in case).
I decided that I would use the 7+ years of dance class experience to good use, and I came up with a (sort-of) dance of all the end behaviors.

As I'm sure you know,  the end behavior of a polynomial depends on two things: the degree and leading coefficient.  If the degree is EVEN, both arms go the same direction.  If the degree is ODD, they go the opposite direction.  This is the first thing I established with them (Remember, odd means "different", so the arms go different ways).  The direction is dependent on the the leading coefficient.  As long as they could determine the degree and leading coefficient, the students could use these four moves to remember the end behavior.

The first is an even degree with a positive leading coefficient.  I shortened this to "even and positive".
It looks like a referee after your team scores a touch down (which is a positive thing, by the way).

Even/Positive

Next, is even and negative.  For this one, flip the "touchdown" sign upside down.  I call this one "no goal" or "no touchdown" (which is negative for your team).  It could symbolize dropping the ball before scoring.

Even/Negative

Next is odd.  This is where the pharaoh description comes in.  The odd degree polynomials look like the arms of a person doing the pharaoh dance.  You can figure out a way to help them remember that a positive leading coefficient goes up on the right and negative goes up on the left.  I told them that Ms. Avery is right handed, and I think very positively about my right hand.  Using my left hand would be a negative thing.  Of course, you can use what you want.  I would love to here what you come up with in the comments.

Odd/Positive

Odd/Negative

                                                                                 

      **Remember that your arms are a mirror image for your students, so you might want to turn around when demonstrating the moves.**

The final product is four moves that they can do on command.  The dance in order sounds like...

"Touchdown (1st move), no touchdown (2nd move), pharaoh (3rd move)...dance (4th move)"

I also called out random descriptions, and they had to show me the move.  I have a video that I might post later.

Happy Dancing!

Yummy Math - V"fun"n Diagrams

In my Advanced Mathematical Decision Making class, my seniors are a challenge to keep engaged.  During a unit of probability, we discussed Venn diagrams and how they are used for probability.  I could tell that they were getting tired of drawing boring circles for each situation.  Finally, I decided enough is enough.  We are going to make V"FUN"N-diagrams.

The task was to create a situation that would use a Venn diagram to represent and come up with a creative way of symbolizing it (no boring circles on paper).  Because they are high-schoolers and because they could, most of the groups did food representations.  They also had to determine 5 probabilities using their Venn diagram situation.  The groups all presented their situations, then we enjoyed!  It turned into a pseudo "food-day", but I felt that it was needed halfway through the semester.  It increased morale, and it really got them involved in the math.  Small price to pay for creativity and awesome math.
Here are some examples of what they came up with...

People who like yellow Powerade, blue Powerade, and both.  The mix was surprisingly refreshing!

People who like sugar cookies, chocolate chip cookies, and both.  As you can see, they did some extra decorating...



This situation was not perfect (cheese pizza, pepperoni pizza, and both).  Technically, this could not happen unless the pepperoni side had ONLY pepperoni (which it didn't).  I understood what they were trying to say, and it also caused a very interesting discussion.  I'm including it because it looks awesome.  It was also very delicious.

This may look like a regular pie, but trust me, it is not.  Half of the pie was pineapple and the other half was apple.  The middle was a mix of the two.  Homemade from a student's kitchen.  (The student actually had his mom make it..I can't complain)



Brownies, chocolate chip cookies, and both.  The brownie/cookie was the hit of the day.  Very creative!

 I actually don't remember the situation for this one, but I liked how they used an every day object to represent their situation.  They also included numbers and labels on their diagram.  The visual was very powerful to those who still struggled with the idea.

These are just some snippets of what the students came up with.  There were many others that were very creative and well thought-out.  I was a proud teacher.

Happy diagramming!

MATHpardy (A better version of the Merv Griffin classic)

Let me start by saying...

I HATE reviewing for tests.  I hate having to reteach/repeat the material that we have been going over for weeks.  The classic review worksheet doesn't do it for me, so I sought out a way to make my life easier and more fun.  Mathpardy helps me accomplish this.  I found a template online and adapted it to fit my needs.  I have used it a few times since I've found it, and I've had great success.

Every class is different, and the way you decide to run the game should be based on your classroom structure and individual students.  I split my 30 person classroom into 5 to 6 groups (hopefully, you can do the math on the number per group), and had them come up with group names. For each question, each group turns in a sheet of paper with their answer to the problem and their group name.  If the team gets the answer correct, they get the points.  You can do negative points if you so choose.  I use a creative way to determine who picks the question. (First to ________ gets to pick the problem).  I also limit their time based on the difficulty of the problem.  If the paper is not in my hand before the buzzer, they foreit.  The reason I like this method is the student engagement.  Playing Jeopardy the way it's intended leaves some groups out of the running for points.  Therefore, they don't attempt the problem.  This method makes every group work on every problem.

Of course, the winning team receives generous extra points on their test!

My juniors love this game.  No joke.

The verison I have attached is from an exponential unit.  It covers rules of exponents, converting between radical and exponential form, solving radicals, and simplifying radicals.

Again, you can edit the game for your needs and topics.

Happy Reviewing!

Parent Communication

If you are a teacher, you know how important parent communication can be.  Sometimes, a student's motivation comes solely from their parent's influence.  Also, it's good to have documentation for your own sake.  The dreaded "I didn't know my student was failing..." happens way too often, and this could be a way to avoid the situation.  Save all emails and jot the date, student, and purpose on this simple log, and you are teacher of the year! Keep in an easily accessible place, and don't over complicate.

I kept this form simple on purpose.  Don't make your life harder than it needs to be.  That's my motto for happy teaching!!
