## Quadrilaterals INB Pages - Part 2

I shared the first part of my quadrilaterals unit a couple of months ago.  I didn’t share all of the pages though!

I still need to make decent pages for kites and trapezoids.  I had my students just take notes in their notebooks.  I want to make something better for next year.  I had my students do LOTS of practice with the different properties of special quadrilaterals.

First, I had my students fill in this family tree for quadrilaterals.  I had another separate family tree page for special parallelograms, but I forgot to take a picture of it!  This family tree is part of my Special Quadrilaterals Always, Sometimes, Never Card Sort.

On the next page, I had my students do the card sort in their notebooks.

Then, I gave my students this sheet for them to check off the properties in columns.  It’s part of my Special Quadrilaterals Properties Cut Out Activity.

On the last page for this unit, I used quadrilaterals task cards as review problems.  I had students glue the task cards in their notebooks and write the answer off to the side.  I shrunk the task cards when I copied them, so they would fit into their notebooks nicely.

These pages were a good review and wrap up of the rest of the unit.  Kids have so much trouble keeping the properties straight, that I try to do as many activities as possible!

## 6 High School Teacher Must Haves - Guest Post

I am very excited to be writing this post today as a guest on Mrs. E Teaches Math! Mrs. E's blog is one I have followed for many years, so this is a great honor. There are so many things I'd love to buy for my classroom, but then I'd be broke! In this post I narrowed it down to the 6 things I can't live without. If you or someone close to you just landed their first high school teaching job, congratulations! After so many years of preparation, this is a very exciting time. We have all seen the memes about how much money teachers spend on their classrooms, but it doesn't have to be that way. Here are 6 things that would mean a lot to a new high school teacher.

1: A Mouse
This one might seem silly, but it makes a world of difference. Chances are, you'll be issued a laptop of some kind. When I taught in Boston, we were given Apple computers that ran Windows because of some law suit about one or the other monopolizing education. It was so weird. It was also really awkward! Even more awkward with any laptop maneuvering the touchpad mouse while trying to work at the necessary light speed in order to get everything done. Having an external mouse cuts down on a whole lot of unnecessary frustration.

2: Magnets
I'm not talking any old magnets here. I'm talking those mega magnets tough enough to hold half a ream of paper onto that 1992 magnetic whiteboard. These strong disc magnets are super cheap on Ebay and are so versatile in the classroom. They allow for student work to be displayed, which makes student engagement go way up. Magnets are also awesome for displaying a whole host of other things, like scavenger hunts, anchor charts and group directions.

3: Panel Board
This might also be called "tile board" at Home Depot. It's an 8-foot by 4-foot slab of shiny white board that, after being cut into sections, works great as personal student white boards. Whenever I need a quick filler activity or if my students are just not focused, personal white boards are a lifesaver. The ones sold at teacher stores are SO expensive. Panel board is almost as good and a whole lot cheaper. If you have no way of transporting the big sheet and/or can't cut it at home, Home Depot will cut it for you. I chickened out and only asked for mine to be cut into 8 sections, which were a little big but did work great for group work presentations. I am sure by asking nicely you can get more sections cut  Though a whole lot cheaper, panel board is not as durable as the personal whiteboards you can buy at a teacher store. A good workaround is a layer of dry erase paint at the end of the 2nd or 3rd year. This post from Alex at Middle School Math Math Man shows how dry erase paint can be used to make a dry erase table.

The paint can also be used to spruce up personal whiteboards. Also, some teachers like to edge the cut sections with something like electrical or washi tape.

4: Quartet Dry Erase Markers
Everyone raves about Expo markers. I've found that the smaller Quartet markers, like the one in the photo, work awesome on personal whiteboards. They seem less scratchy, which helps the boards hold up, and the ink seems to last longer. This past year I laughed when I overheard a teacher's, "Whoa, what is this?" after being impressed with a Quartet marker. Usually the school will provide some dry erase markers, but never enough for all year.

5: Flair Pens
This one is such a teacher stereotype, but no doubt deserves its place in this top 6. For a long time I resisted the flair pen with an, "Ugh, like I'd fall for that trend!" Boy was I wrong. What makes them so great, and what I hadn't ever understood, is that the color is super bold yet, by sheer magic, doesn't bleed though the paper to the other side. They are the perfect grading pens. I can check all the correct answers I want on one side of a kid's paper and nothing goes through to the back. Awesome and mysterious!

6: Document Camera
This one is the most expensive on the list and may not be a must for some, but I love my document camera for so many reasons. When a student is out and will miss notes, I can give the class notes under the document camera so that the student can have the filled-in sheet the next day. My document camera lets students share their work and for us to discuss it as a class. When my graphing calculator software is acting up, which is usually, I can put a graphing calculator under the document camera and continue with the lesson.

What must-haves would you suggest to a new high school teacher?

## Functions, Tables, and Graphs INB Pages

I used these interactive notebook pages during my functions unit in Algebra 1.  It built on my student's previous knowledge, which I loved!

There are three main parts on the notebook page.

First, I reminded students of the definition of the words "discrete" and "continuous".  They learned these words in Pre-Algebra and in science class.  However, I wanted to make sure they were in their notes.  Then, we completed a foldable relating an equation, table, and a graph.  I also had students label key features of a graph.

After we completed the different parts of the notes page, I had students practice with a partner on a practice page.  I copied the page at 80% so it would fit in their notebook.  I could have left it full sized and used it as homework though.

This is what the pages look like as a "spread".  I like to plan pages as a two page spread, like a newspaper.  :)  To keep my students interested, I copied everything on different colors and I let them choose what colors they wanted.  Honestly, I dropped a stack of colored paper on the way to the copier, so I made it work ;)

You can find the foldable and practice page here.

## Arc Length vs. Arc Measure

Students always seem to get confused about the difference between the length of an arc and the measure of an arc.  When I teach this concept, I try to relate it to sports.  The vast majority of the kids in my class have run around the track at some point.  So I start asking them questions. :)

If you have to run one lap around the track which lane do you want to run in?
The inside one!

Why?
It's shorter!

Why?
The circle is smaller.

Interesting...  You have still run one lap though.  All the way around the circle would be 360 degrees.  So, it should be the same distance.  If you run the outside lane, that's the same distance as the inside lane.
[At this point, controlled chaos ensues.  Most of the athletes become indignant.]

Then, I tell them that the measure of an arc is the degree measure.  The length of the arc is the actual distance you would have to run.  Most of them get it by this point.

I made a handy little "cheat sheet" for students to glue in their notebooks.

## Coordinate Quadrilaterals INB Pages

Instead of teaching coordinate quadrilaterals throughout the quadrilaterals unit, like I normally do, I taught it all together.  It worked.  I don’t know if it was better or worse than doing it throughout.

The first day, I only taught about proving a quadrilateral is a parallelogram.  Before I started the lesson, I gave all of my students a sticky note and had them find the formulas for midpoint, slope, and distance and write them down.  They stuck it on their desk and referred to it during the lesson.

I felt super fancy with the foldable I used for this lesson… partly because I used an “I can…” statement on the foldable, and partly because I used a shutter fold, but kept one flap up.  I also feel like the way I have a flap for each formula takes any guess work out for the students.  Under each flap, we worked the example, using that method.  So, when my students had their homework they could mimic the work under the flap.

On the facing page, I gave students a scrap of graph paper.  I gave them the four points in the margin and had them draw the graph.  The worked with their partners to prove it was a parallelogram using all three methods.  I honestly didn’t have to use the graph, but I think it helps them visualize things better.

The second day, I taught students how to determine the type of quadrilateral, using coordinate geometry.  Some of these problems take up so much room (if you want things to be organized), so I used a giant hamburger book.  There were three problems in this book.  It took almost the whole class period to work the three problems - that could be because my students worked slow.

The third day, I had my students do a stations maze to practice their coordinate geometry.  They worked on it the whole class period.

I haven’t decided if I will teach it all together again next year, or if I will do a little at a time throughout the unit.  Good thing I have time to decide!

## Systems of Equations INB Pages

This year, I taught systems of equations right after Christmas break.  My students STRUGGLED.  I think I need to do a two-day review of graphing equations before jumping in next year.

First, we talked about what a "system" of equations actually is.  We also talked about the three types of solutions they could have and what they looked like graphically.  At the bottom of the page, I included a magic book that substitutes points into a system to determine if they were a solution.  The file was corrupted so I will get to remake that for next year.  Yay.

Next, we solved systems of equations by graphing.  I gave the students a step by step list for their notebooks that had one example included.  Next year, I think I will include a "drill and kill" practice sheet on the facing page.

The next day, we solved systems of equations by substitution.  I used the same step by step list with one example format as the previous day.  This one worked well and I liked the way I highlighted what we were substituting into each equation.

On the next page, I had a practice sheet.  Each time I substituted into an equation, I highlighted the substitution.  Showing that helped my visual students SO MUCH.  I also started throwing in word problems.  They hated me a little for that. :)

I spent the next day reviewing and showing them what the special cases looked like algebraically.  No cool foldable for this page.

I continued following the same format for solving systems of equations by elimination.  I had a step by step list with one example for their notebooks.  This time, I highlighted the "stacked" variables.  I was trying to make them notice that they needed to make sure they were combining the same variables.

The example page came next.  I continued highlighted the "stacked" variables.  Also, more word problems :)

We had several days of review and when I was sure that my students had it down, I pulled out the big guns...MORE WORD PROBLEMS.  I used legal paper to make a giant hamburger book.  It gave us plenty of room to work all of the problems.  My students whined loudly that they were going to die.  No word problem-related deaths... yet.

## Factoring INB Pages

I teach factoring a little bit differently than most people, I think.  I only teach one method and it works every time.  There's no need for boxes or fancy flow charts to tell students what to do when.  You can read my post about How I Teach Factoring.

For this unit, my interactive notebook pages are kind of bland.  However, they got the job done!

First, I taught factoring by grouping.  I listed the steps to factor by grouping, then had an example below.  Inside the hamburger book, I have lots of examples.

Next, I taught factoring trinomials.  I had the steps listed and an example below (again).  Inside the giant hamburger book there are a bunch of examples.

Lastly, I taught all those special factoring patterns...sort of.  There really isn't a need for students to know all the factoring patterns, until they notice the pattern for themselves.  They can still factor everything (that's required in my Algebra 1 standards) with the splitting the middle method I've taught them. This hamburger book lays it all out for them.

Yes, this unit had only three lessons.  Our textbook has an entire chapter for this unit!   We did a lot of practice, so we spent more than three days working on these skills, but it wasn't necessary to teach a million special cases.

I hope this helps you maybe re-think your factoring unit!
