Fav Fridays!!!

I don't have anything of great mathematical
use for us today.

But I would like to talk about my favorite place to be on a Friday night at 7:30.

I was born and raised in the south and we care about two things down here in the Bible Belt. Church and FOOTBALL!

So on Friday night's at 7:30 the greatest place on earth to be is at a HS Football Game and for me as a Coach is to be with my students coaching them, win or lose. It's the best scene ever!

Here are a few pics.

### Made 4 Math : Notebooks - Pair-Up

Our Algebra 2 Classes have been studying Matrices and last week my Math Support class needed help with Inverse Matrices. They wanted to work with a partner and I needed to keep them focused. SO.........................

I put problems in Envelopes, and I gave each group one.

They had to pull out the problem and solve.

Once they passed it on, they used the next card to check their answer on the back.

I gave the kids 4 minutes per problem and then we rotated. Allowed me to walk around the room and help certain groups and they stayed on task!!!

### Fav Friday: Matrices Pass Around.

Fav Friday: Matrices Pass Around

There are almost no Matrices activities for the classroom, I don't know why, but if there are I can't find any and trust me I have been looking. I may be adding Matrices activities for a while in the hopes, that someone likes them, uses them, edit them, make them better, and pass them along.

Here is my first stab at it. It's a Matrix Pass-Around (Rally Coach). Put your students in groups of 4.

The 1st problem is scalar multiplication.

2nd problem is subtraction.

3rd problem is matrix multiplication

4th problem is Inverse matrices.

For my purposes I made my kids do problems 1 and 2 by hand and 3 and 4 they had the option to use technology (calculators :))

### My Fav Friday - Graphing Cartoons

My Favorite Friday - Graphing Cartoons.

I first got into blogging by finding a website named Dan Wekselgreene, named exponentialcurve.blogspot.com. I have no idea on how I found him, but I did and it changed me as a math teacher and wanted to make me express my ideas as well.

One of Dan's best activities, IMO, was a comic strip lesson he taught on graphing lines since his students were still struggling with it. You can find the lesson here Language and Retention of Math Concepts

He had his students draw comic strips to express the different ways to draw lines, when slope is zero, b is zero, negative slope, etc.....

I look his idea and used it in Algebra II class. I used it in my Exponential Graph Unit. My students have to sketch exponential and log graphs and transform them and many of them struggle with the transformations, well here come in the comic strips to the rescue.

I had my students take them and graph 1 exponential growth, decay, shift up or down, and 1 shift left or right. Here are some examples

I plan on using this idea more and more to help my students with graphing and transformations since it is still a part of the Common Core Curriculum.

### Math Posters

I so meant to do, Made 4 Math Monday, but it was Labor Day and I was busy watching my Yellow Jackets blow a football game :(.

I use to be the poster king, but when I transferred schools, I left posters to my collab teacher who was moving to a resource setting. So my wall was naked :(.

Didax Education produces some wonderful Math Graffiti Posters. They can be found here Posters

But the cost is outrageous! 75 dollars for 50 posters. So I went to store that is free, my students! Here are some of their creations that now hang in my room.
