### A peek at my Pythagorean Theorem Unit

At last, my finalized Pythagorean Theorem unit. I feel like I have been working on this forever. I love all of the activities that I have found and it was difficult to narrow it down to the following lessons. Here is a list of the major activities that I am doing with my students starting next week. This is going to be fun!

### Pythagorean Theorem Investigation

I will introduce Pythagorean Theorem with the Starburst candy activity. I was inspired by Pam Lucken's video to use Starburst candies as a manipulative to form the sides of the triangles. I have seen the same project using other manipulatives as well. I just think candy will be fun. My goal is for the students to be able to discover the Pythagorean Theorem on their own. When they have finished the activity it will go in their interactive notebooks.

Students will need:
•   A copy of the Starburst Triangle Investigation and direction sheet.
•  A plastic bag with 340 Starbursts in each bag. (Maybe 350 to account for accidental eating.)
•    A plastic bag with triangle measurement sides for the six triangles they will model.
•    Paper, pencil and straightedge.

Triangle Exploration Worksheet ( adapted from Alexander Sabitino, Picking Pythagorus.)

starburst triangles to measure pg 2

My students will follow the directions on the Triangle Exploration worksheet and create triangles with the side lengths given on the cards in their envelopes. They will determine if the sides form a triangle, classify what type of angle is formed by the largest angle and if the area of the smaller sides cover the largest side.

### Pythagorean Theorem Foldable

The next day we will make this foldable and place it into our INB'directions for Starburst activitys.

### Interesting Lessons

Time for some interesting problems from Mrs. Hester's Classroom and Embrace the Drawing Board. Check their entire lessons on the link provided. I love these two lessons.

And here are some more wonderful INB pages from Mrs. Hester's Classroom.

Lesson Will the TV fit, from Tim's 3 act from Embrace the Drawing Board.

### Pythagorean Triples

In the past, Pythagorean Triples have been one or two problems where the topic has been mentioned and not much more. I plan on spending a few day on triples this year.

OK, I don't have this foldable completely finished but thought I would give you a preview. Final foldable will be posted soon. Promise!

### And here are some videos.

I love Robert Kaplinsky - Wizard of Oz, Pythagorean Theorem problem. See if you can find all the errors in the video before looking at his answers. I can't believe that so many of my students have never seen this movie. I may be dating myself but we watched it every Thanksgiving when we had only 4 channels to watch on TV. My how times have changed.

Some teachers would probably use this at the beginning of the unit, but I want my students to have lots of practice with Pythagorean Theorem before they see this video. I am going to use it at the end of the unit. They will have practiced many times and be able to verbalize or write down the errors they see.

And of course, Dan Meyer's 3 act, taco cart lesson. Check his site to see all 3 acts with questions and more. It is outstanding and the kids love guessing to see who will get to the taco cart first.

### Distance Between Two Points

I'm excited to use Mary's lesson distance between 2 points at Curiouser and Curiouser. Read Mary's post to see the rest of the lesson. I'm hoping that the hallway outside my classroom is large enough for this. If not I will go to the main hall of the building. I like how the students will need to decide how to measure the sides. I've already started to think about how to group the students for this activity so they will be successful. Thanks Mary for posting this lesson.

I know that I will  add to my plans throughout the unit. My lesson plans change depending on the students needs. Look for photos of students in my next post.

Til next time,

### A look at my classroom

I always love looking at how teachers decorate and organize their classrooms. Now I am going to admit that there are areas of my room that I am not willing to show you right now. Like my desk. UGH! As much as I try everything gets piled on top. Yes I am a person with organized piles. Part of my problem is that I teach Pre Algebra first, then switch to Algebra, then back to Pre Algebra, then a teacher comes into my room for 2 periods and I move stuff, and then back to Algebra. As hard as I try I can't help but pile. Poor Ric comes into my room with his cart, (he is in different rooms all day), and he has a little section that I have clean for him. Anyway, I am trying to get my room organized but there are certain areas I have already that work well.

Assignment Area

This is the assignment area of my room. There is a box with files for Algebra and Pre Algebra with a calendar above for each class. I write down what we do each day and if the students are absent or need extra sheets they can come to this area and get what they need. We also have calendars for each unit that the students receive and there is a folder on the bulletin board where they can get extras. This puts the responsibility on the students when they are absent or loose work. Next year I am thinking of having a blog for each of my classes as well.

Schedule Area

I saw this somewhere on Pinterest and liked it so I made my side board an area where the objectives, vocabulary and schedule are listed for the day. What is up here is not complete. I usually have the Common Core Standard listed and vocabulary as well. I know that some people love chalkboards and I have 2 large ones in my room. I use to have the entire class go to the board but after a period there was nothing but chalk dust everywhere. And no, dust free chalk does not exist. There is always dust. The kids would put it on their hands and there would be hand prints on everyone's backs. Gotta love middleschoolers. I just quit using them and make bulletin boards out of them. Wish they were white boards.

Who knew duct tape was such a decorating tool. This has held up for the entire year even with being washed every once in awhile. You can't see all of the posters above the chalkboard but they are from Sarah at  They are very inspiring.

Displays of Student Work

Here is my other large chalkboard on the opposite side of the room. I use it to display student work. There is a section for each class period and I change it often. Believe it or not middleschoolers love to see their work on display. My desks always start out in straight rows but we move them around every day. Because I share a room with another teacher I have to have them arranged this way for him. I so want to have tables! There are four in my room and I keep trying to get more. I am fortunate to have the largest math room and I am grateful for that. It allows me to have desks and a few tables. The kid friendly mathematical practices yellow posters above the chalkboard are from Sarah at Everybody is a geniusI love them!

I'll try to take more pictures and post them soon. My goal is to clean my desk area and be able to take a picture of an unbelievably organized and workable area. LOL. One can always hope.

Til next time,

### Pre-teaching before Pythagorean Theorem

The Pythagorean Theorem unit is going to be so much fun to teach this year. I have never had the time to go into this topic with the depth that I plan to this year. There are so many great activities it is hard to narrow it down. My Pre Algebra students need to review some of the prerequisites for this unit so I took the 1 1/2 before spring break to review some of these concepts.

1. Measuring and Classifying Angles
The students always love working with the protractors and after 4 long days of state testing it was exactly the type of activity they needed. We measured and drew angles adding these pages to our INB's. This foldable came about by accident. When I printed up the flash cards for perfect squares and square roots (see below) there were empty flashcards on the last page. I printed the flashcards on card stock and couldn't bear to not use it. In my mission to use scrap paper, I created this foldable. :)

 The students used protractors to draw their own angles where the green post it is.

I love utilizing materials that I have. In hindsight I may arrange these horizontally next year so they all fit onto one page.

2. Measuring and Classifying Triangles
We completed this foldable and practice sheet from 4mulaFun  for our INB's. It was a good review of triangles for the kids and they are getting so much better with the cutting and pasting  activities. I finally gave up on glue and have the students tape their foldables in their notebooks. They were a nightmare with the glue, it was everywhere and the tops would get clogged. I used glue sticks but they didn't last long at all. Tape is expensive so any ideas from my readers is appreciated.

3. Sum of the angles of a triangle.
I didn't really need to review this topic for Pythagorean Theorem but my students background is lacking so as long as we were talking about triangles and angles, I added this in for them. I can't believe I never saw this activity before to show the sum of the angles of a triangle equal 180 degrees. It takes no preparation on the part of the teacher and I used paper from my scrap basket. YES! I had the kids take scraps of paper and draw an acute triangle, right triangle and obtuse triangle. The size or angle measures were up to the kids to decide. Then they colored or marked all the angles of the triangles. I then had them rip the angles and reassemble them to form a straight line. So easy and a great visual for them. It took a few tries to get the angles lined up so it is like a puzzle. They loved it.
 Tear the triangles into three pieces. Then assemble to form a straight line.
 A great visual for showing the sum of angles of a triangle.
Yes, I know the top triangle isn't lined up in a straight line. Funny none of the kids caught that! Not to worry, I will fix it.

4. Creating a geometry star
It was the day before spring break and nobody wanted to be at school. There was an assembly and the classes were shortened to 36 minutes and the kids were, you know, a bit excited. What to do? Since we were studying triangles we did this quick project. Most of the kids finished in the 36 minutes and they were busy the entire time, calm and happy. Isn't that the way it should be before break? Again, I like this because all that was needed was paper, pencil, ruler and colored pencils. Easy. And it gets better, it is free on teachers pay teacher from Virtually MontessoriAfter break I will post some of the pictures the students created.

5.  Square numbers and square roots.

We are making flash cards to memorize perfect squares and square roots. You can go to kitzkitz  to make your own flashcards to print. We  will cut the flash cards and then put them into envelopes in our INB's. This idea is from Mrs. Hester's Classroom. I only had the kids do the perfect squares for this lesson. They learned this very early in the year but now I have them memorize the squares through 25. The envelope to make the pocket is from homeschoolshare. They have a fantastic collection of templates you can use that are free. They also have templates for foldables that you can type on and print up. Check them out, they are a great resource.

Here is the link to the flash cards for perfect squares and square roots (make sure to download the document to see square roots as well.) The originals are large and good for a math center but they use seven pages of paper. When I printed the individual flash cards for the students, I printed 4 pages on one page. That way I only used two pieces of paper per student. I'm always trying to save paper when possible.

 I gave the students  the smaller version of the flashcards and they fit in the pocket nicely. You could also have two pockets instead of just one.
I hope there is something here that is new that you will be able to use. One thing I am noticing with Common Core is that everyone is teaching the same topic at the same time so there is so much available for us to use with the kids. It is amazing. I am finishing up my Pythagorean Theorem unit and hope to post it by the end of the week.

Until next time,

### Blueprint lesson #3

You know how there is a lesson that you just know is going to be great. I mean it will be so great, right? You can't wait to have the kids come to class and just absorb all of the awesomeness of the project. They come in and all of your best laid plans just flop! UGH! Well that was my blueprint lesson. These blueprints were just too difficult for the kids to understand. They gave it a good try but I have to go back to the drawing board on this one. Literally. I need to have more structure to the lesson and perhaps start with having them make some  basic blueprints first. I don't want to give up on this idea because there is so much here that the kids can learn. So I guess I am going to drag all the blueprints home over the summer and create very specific assignments for them. I did change my plan and the students measured angles and classified them. I am going to have them design the outside of a house using the angles they measured. Our spring break started today so after break if time permits.
Here are some pictures of the kids at work. It turned out to be a good experience for them even though it wasn't what I expected it to be. Making it more focused will help.

 This group of boys were very engaged.

 Hmmm. Interesting picture.
 So here they are trying to figure out how to read all of the information on the drawings.
 This group tried hard to come up with some good questions.
The one thing about teaching is that everyday is different and this one certainly was. Now it is spring break, time to relax and read a book! What a treat.

Til next time,

### Housing Blueprints - Day 2

Today was the last day to connect with students before I have to post grades for third quarter so I was not able to start my blueprint exploration with the kids today. I was able to post some of the blueprints around the room and my students were very interested in what we will be doing with them. I also placed a couple outside my room on the bulletin board for the other students to look at. As you can see there is so much that can be applied to math. We could say everything in these blueprints applies to math!

### This blueprint screams slope to me. I hope the kids see that as well.

This blueprint has so many area and volume components to it. Love it!

This one is a little hard to see but it is stairways and doorways.

It will be fun to see what the students create for their problems. I have a feeling it is going to be one of those busy, exhausting, but great days.

I'll post again tomorrow.

### Housing Blueprints

I am fortunate enough to have blueprints of all the phases of building a house. (My husband's occupation.) I had these laminated and I post them around the room. The day that the kids walk in they are so excited and just want to spend a day looking at everything that is on them. There is measurement, scale, proportion, slope, area, volume, and the list goes on. I have 15 different blueprints in total and I just don't have the time to drag them home and make problems over all of the various units. This is the last week before spring break so I have decided to use the blueprints as students exploration lessons for my Pre Algebra students.
The students will be in groups of 4 and given a sheet to create 2  math problems related to the blueprints. I will have rulers, protractors and dry erase markers available at each station. We will have a short discussion of all the possible topics for their questions.  The students will be able to make questions that are based on their abilities and I will steer them to the levels I think are appropriate for them. I may even assign different topics per group. One group may measure the perimeter of the driveways where others will have to create a problem to find how much asphalt will be needed to construct the driveway. Some may find the slope of the roofs and others may find how many shingles will be needed to cover the roof. I am excited about this because the kids will create the questions for me and then I will have a bank of questions to use for future lessons. YES!!!
Check back tomorrow and I will post some pictures of the blueprints and my classroom. I will post some of the problems the kids create in next weeks post. I am excited and I know they are going to love this lesson. I wish I could make a copy of the blueprints but they are so big. If there are builders in your area maybe they will donate old blueprints to your school. Let me know, I would love to see how you apply these in your classes.

Til next time,

### Pythagorean Theorem - Real Life Lessons

I have been searching for some real life application lessons for Pythagorean Theorem unit. You know the lessons that students can relate to, not the ones where you have a ladder placed against a building. I have found a two lessons that I absolutely love.

The first is Pythagorean Theorem map lesson and it is exactly what I have been looking for. How often do our students actually handle a map and measure it?  And she uses a map of the town the students live in. Now that is something they can relate to and understand. I am sure there is a lesson that could be developed using technology but that will be for a later post.

Mrs. Hester has students find how much cable AT&T will need to install U-verse lines in the town the kids live in. Unfortunately there are not many straight roads in the town I teach in. UGH! No wonder I get lost in this subdivision when I decide to take the back roads as a short cut. I'm determined to find a spot in this town that has straight roads. Until then I may just use Mrs. Hester's map. I love this lesson!

The second lesson is Tim's 3 act, TV space at Embrace the Drawing Board.

In this lesson, Tim has an area below a shelf, between two speakers and on a stand that he wants to place a TV. Will the Samsung TV fit in this space? Tim has more pictures with measurements and discussion questions. This again is the real life experience problems I am looking  for my students to do. They can relate to the problem and who doesn't want a big screen TV? Thanks Tim for this awesome lesson.
As I have said before, I don't think I am a very creative person but I don't have to be. There are so many wonderful lessons out in Blogland that I can pull for my students to use. I don't need to spend hours making them, I can adapt the lessons that others have so generously shared. If anyone has other Pythagorean Theorem lessons they know of, please share them. I would love to see more of these.
Til next time,

### Retesting - a new idea for me

This year after reading several blogs, I decided to let students retest if they wanted to. After all what is my goal for my students? I want them to learn the material and since all of math is built on previously learned skills they should retest. I did put some parameters on the retest. The students need to fill out a form, reflect on what they need to learn and do 3 activities to improve their knowledge in that area. The 3 activities need to be stapled to the retest form, along with their test and reflection. One of the activities can include a tutoring session with me after school. The other 2 are on their own. They can not retest until all of these steps have been completed. There is a 2 week window to retest.
So how has it worked so far? The students who have completed the activities and retested have improved their test grades about 2 letter grades. I was impressed at that improvement. Some students tried to sneak in assignments that were done in class already. (Of course they had to try didn't they?) Guess what? If they did not do the activities the test grades stayed exactly the same. I mean they didn't improve their grades at all. Now I check very carefully to make sure they are new activities. Sarah at Math = Love has a great form that I have used this year, (thanks Sarah), and I shared it with the teachers in my building. Kathryn Smith, one if our reading teachers, revised the form to create this newer retest form. The original looks better as a few of the lines are missing on this picture.
