Algebra 2 Unit 2

Our second unit in Algebra 2 is on Linear Relations & Functions. This unit is my green unit so everything I copied was in green except for a mistake white foldable : (

Our first set of notes was just an into to functions and relations. I got these graphic organizers here. We did a cut and paste activity where they had to identify the difference between functions and not functions. Then we used this awesome domain foldable. I don't think I referred back to it often enough for students to use it. These notes definitely took longer than I had intended.

Next these notes were pretty boring about linear equations. Students first practiced graphing intercepts to form lines.

These notes are about slope and slope formula. Since slope should be a review for Algebra 2 students we combined Parallel & perpendicular slopes as well. I stole the name idea from Sarah at Math Equals Love and had students identify the slopes when writing their name in straight line letters. She has a bunch of great slope pictures here.

We finally then moved onto Slope-Intercept Form. Students always remember y = mx = b but don't know how to use it or what the letters stand for. I love this foldable I found on TPT here. It has a place to model one problem for the students and then have them try one similar. It also organizes the different information a problem might give them into three doors.

Piecewise Functions were a really difficult topic for my students. When we did problems for warmups or classwork I gave them colored pencils to shade in the the area for each piece and then draw the line in the matching color. One difficulty they also had was deciding the closed or open circle where the functions met.
I got this foldable on TPT here but really am not in love with it (I had to write on the outside of the doors myself and the title on top was hard to cut around) I may remake something next time.

Here is the foldable that should have been printed on green, but at least its white and not yellow or pink. I got it from Sarah here. I like that we started with the parent function so they could see the shape and graphed points to move them around.

Lastly in this unit was Linear Inequalities. I really enjoy these and I should have made something to glue in for the chart to decide solid/dashed and above/below. I've used this little chart for a couple of years though and I think it helps.The foldable came from TPT here. I Like that 2 examples are in slope intercept form and two are not so they have to rewrite them and not rely on the sign. I also like that they circle solid/dashed and above/below before they start.

That's it for unit 2 on Linear Equations & Inequalities.

Algebra 2 Unit 1

So this is my first unit for my Algebra 2 Interactive Notebooks. I color code each unit so everything here is pink including any quizzes and the test. I do copy any worksheets on white paper though. As another disclaimer most things in my notebook are happily borrowed and bought from other bloggers or TPT and I will do my best to link each one.

Here is my Unit Table of Contents that goes in the front of our notebooks. (I link to this in my previous post) I start by showing the students this page with the day's title written down and while they copy and title/number their pages I collect the homework they passed forward.

We start off with some order of operations review. This graphic organizer is from Sarah (MathEqualsLove) and can be found here.

Then we move onto the real number system. These graphic organizers can be found here.

Solving equations comes up next. The properties organizer can also be found at the link above. The words denoting add/sub/mult/divide I found by searching online and couldn't find right now but I will look again.

Absolute value equation notes are a little boring. I love the Frayer Model for vocabulary but they suck to cut all out. A set of six to a page can be found at the same place as above. (Thanks Sarah for all you let us borrow).

Solving Inequalities got this fun foldable. It can be found here.

For compound inequalities I bought a few things on Teachers Pay Teachers and are linked here and here.

That is it for Algebra 2 Unit 1 on Equations & Inequalities.

Interactive Notebook!!!!

So this year I went full interactive notebook in my Algebra 2 classes. Everyone does them different and I don't think there's a right or wrong way to implement them, but I just wanted to share mine. The downfall of interactive notebooks is how much time they take on the preparation side so that leads to my disclaimer: I happily borrowed and bought many many many of there ideas from other bloggers and TPT. I will try my best to link each and every one of them but may forget where I got a few :)

Here are a few pictures and details on how I set mine up and how I organized them.

First I had my students purchase a composition notebook ( a few had non composition books and they fell apart) And on the outside I had them write their name, class and period. I made a book along with each and every class (3 periods).

On the inside cover each student pasted a notebook rubric. ( Kids get so mad when I took a point off for skipping a page. "But it's right there in the rubric," I say) I found this rubric here.

On the first lined page I had students create a "Math About Me" page where they had to have at least 8 numbers that pertained to their lives and had to add some color. (Along with their names again and the class period)

Next year I want to create my syllabus so it can be glued in on one of the first few pages so the kids have it handy when I refer to a rule or procedure listed in it.

The next 6 pages we saved for gluing in our future Unit Table of Content pages. We had 12 units total in Algebra 2 and we made a new page for each one. I used Sarah's from Math Equals Love here. I used a different color for each unit and then repeated the colors over.

The way that I set mine up on the inside was that we took notes (definitions, formulas, steps, etc. ) on the left hand side and then worked out examples ( or classwork) on the right hand side. This worked well for my classes but I was pretty strict about what we wrote down and didn't give them much option to customize to how they wanted to set them up. It was also a little bit of a pain for my students in AVID who were supposed to be taking Cornell style notes.

Some notes were boring and we didn't always glue something in. sometimes the only thing we glued were examples typed out. 

Inside the back cover we taped down a "bookmark" made from sting. I don't know how many of my students actually used these and may skip them next year. 

For the majority of the year we were using glue sticks to paste in our foldables and such but I noticed lots of papers coming unglued. Once our gluesticks ran out I switched everyone to an elmers school glue and they help up much better. Even though it seems messier I just tell them to use 5 dots (one in each corner and one in the middle).

I collected the notebooks whenever we had a test and counted the table of contents page and each set of notes (left  & right side) as 5 points each.Depending on how many notes we had in that unit the notebook points would vary.

So that's basically how I set them up and I plan on sharing all 12 units individually...wish me luck.

Introducing Exponential Growth

Just thought I'd share how I introduced exponential growth to my Algebra 2 students.

For a warmup assignment I asked my students if they would rather have a million dollars today or a magic penny that will double itself for 30 days. Students wrote down their answer and why, then we took a vote of who would choose each. (most chose a million muahahaha)

We then began the story One grain of Rice by Demi.



The story is about a girl that convinced an unfair Raja into giving her all the rice he had taken from a town by having the amount start with one and double for 30 days.

After we've read about a couple of days we start to guess how much she will end up with and see who's answer is the highest to put on the board.

We finish reading the story and students tend to be pretty shocked that the one grain of rice turned into millions and then billions total.

After the story we filled in this worksheet from Illuminations.

Most students needed a little help coming up with the equations on their own. We looked at and discussed the pattern between the total after so many days and the next day after that together as a class.

Over the next couple of days we graphed, wrote and solved some exponential problems and I found myself referring back to the story quite often. 

I think my students enjoyed the break from math to enjoy a story and it was kinda fun for me to have story time as well. I believe this is my third year now introducing exponential equations this way.

Distance & Midpoint Formula

Just wanted to share an easy way to get your students to practice the distance & midpoint formulas.

Print off a class set of what I think of as skeletons for the two formulas.

Put each paper into a clear sheet protector.

Hand each student the sheet protector, a dry erase marker and something to erase with.

After students have been given the formulas you can give them two points to practice by filling in each step and working down to the answer.

The scaffolding helps students work out each step. The hardest part for them will be adding/subtracting positive & negative integers.

Then for homework assign practice problems without the scaffolding.

My students had a lot of fun working on problems and even asked for a couple more to work on. I've used these a couple of years in a row now so I just keep the papers in the protectors but I have some other papers I change them out to. (synthetic division, graphing lines, box method and factoring by grouping) The sheet protectors are way cheaper than a class set of white boards and its nice to put that paper inside with some steps for them.

If I knew how to upload the files I would :( Sorry.
