### Finding Slope Foldable

It never fails, I start teaching slope and my students have so much trouble understanding the concepts. This year it began right away! So we slowed down, and took time to make this foldable which shows examples of the four types of slopes. When doing the foldables in this unit we have been cutting out small graphs and pasting them in. It just takes so much time. I liked Journal WizardsMy tools for finding slope  foldable, so I used it. The only change I made was to make the foldable out of graph paper. Why didn't I think of this earlier?

The inside of the foldable has examples of the four different types of slope. We graphed and counted rise/run for each problem and then used the  slope formula to find the slope.
 Finding slope using rise/run                 The students will be to use this as a reference on their homework. Love it!

 Finding slope using slope formula

Yes I know I dropped the negative three on the bottom example. My kids caught the mistake and we changed it. Whenever I make a mistake and they catch it I say, " I just did that to make sure you were paying attention." Their response, "Oh sure Mrs. Lichtenberger!" Can't fool them.

Til next time,

### Slope pictures

Here in Chicago we are use to cold, windy winters. This year has been extreme, even for us. Last week school was cancelled for Monday and Tuesday. When I woke up Monday the temperature was 24 degrees below zero! Same thing happened this week on Monday and Tuesday. School was cancelled and everyone in my house was going stir crazy including me. The real problem was I had meetings and a sub on Thursday last week and Wednesday this week. I needed to have a lesson for my sub so for my Pre-Algebra 2 classes I used Sarah from s  lesson, Four types of Slope Pictures.  The students created a picture that included lines with 5 positive slopes, 5 negative slope, 5 zero slopes and 5 undefined slopes. They needed to draw it, label the lines as positive, negative, zero or undefined and color it. They had one period, 45 minutes, to complete it and it needed to be turned in before they left.
Here are a few of the pictures they created. I think they did a great job!

I have a couple of challenging classes behaviorally and always cringe when I am out. I received a glowing report from my sub saying she had a wonderful day with the students that my two challenging classes were outstanding! Wow! Thanks Sarah for the great idea!

### Graphing Horizontal and Vertical Lines ( HOY and VUX)

I love teaching slope but so many of my students have difficulty remembering how to graph and write equations of horizontal and vertical lines. I  like the acronyms HOY and VUX to help students remember this. I have seen foldables on many of the blogs I read, but I wanted to have HOY shown horizontally and VUX shown vertically just as another visual for my students. So I created this graphic organizer.

I keep all of my graphic organizers in a binder and use paper with reinforced sides so the holes don't rip. So far so good.That way I can change the order and add other foldables as needed. This is my first year using interactive notebooks and I have changed the order of my notebook so many times that I lost count.

With so many second language students in my classes the horizontal and vertical visual clues are helpful. Of course I started the lesson with the video of  SLOPE DUDE. The kids think it is hysterical and they will not forget zero or undefined slopes!

You can download and print these graphic organizers by clicking here for the Hoy and Vux graphic organizer, graphs, and practice sheet. If you have problems downloading these please let me know. I'm still trying to figure out how to download from Dropbox. I think I've figured it out ???
