I made it!

I MADE IT! TO SPRING BREAK!!! Well, technically spring break doesn’t start until 3:00 today, but it sure feels like it has started already.  :)

Totally how I feel today: Spring Break

My two week break from posting made me sad, but I truly needed it.  I have so many things running through my head that my head is spinning, but in a good way!

I’m keeping this post short and sweet to say hello and let you know that I didn’t go crazy from the mass chaos at school!  I love that summer is just around the corner. We finished teaching our standards, which is perfect because now I can focus on my PASS review for our state’s standardized test.  It’s always much easier to review than to teach the concepts new, so it’s pretty much down hill from here which means lots more time for posting! :)

Hope you didn’t forget about me!

Spring Break is Almost Here!

Can you tell that spring break is almost here? Between the beautiful weather and the students restlessness, I can sure tell spring break is almost here! I keep telling my self: just a few more weeks until I can rest my sleepy little eyes for a whole WEEK!

My school has  three weeks of school before spring break, but that time will go SO quickly. I’m not sure about you, but it’s a frustrating time because I feel like I’m doing a mad dash to the finish line but then still have to turn around and go back and pick up things that keep falling to the wayside. Fourth quarter has officially started for us too, which really puts the pressure on!

In the next three weeks, my goal I have to several things done:

1. Teach the last unit! (wahoo!)

2. Create our common core review toolbox that will be used as a review for PASS Testing in May (HUGE PROJECT I’m working on! I’m sure I’ll post about it when I’m done!)

3. Finalize logo, send out orders, and collect orders for the 8th grade field day T-Shirts.

4. Get ready and pack for my spring break cruise!

I have a post or two planned that I know I will want to share, however, I probably won’t be posting much else other than those posts in the next three weeks due to the pressure to get some other stuff done. Don’t forget about me if I end up slacking – promise I’ll be back!! :)

20 Pointed Star Project {Extensions and Variations} Part Six

This post is part of my Stellated Icosahedron Project. See part one ,  part two,  part three , part four , and part five first.

As my series on the 20 pointed star project comes to an end, I thought I’d share some extensions/variations that I have students do during the project, depending on the time. The project itself takes about 5 days to complete it self, so these things are above and beyond that!  Sometimes I’ll have these extensions/variations ready so that students can do these for extra credit or to go above and beyond for the early finishers. Yes, some will finish on day four (or even day three!).  Have those students do the following or be helpers for others.

Extensions:

  1. Find the students surface area and volume of the figure.
  2. Create a net of the icosahedron.
  3. Watch videos on platonic solids.
  4. Complete packet with all of the information provided in videos, discussions, and with place for work on the volume and surface area of project.
  5. Create a web quest for early finishers to find out more information on platonic solids
  6. Have students create another 20 pointed star with a variation of the original.

Variations:

I sometimes have the students create another 20 pointed start with a variation of the original. What do I mean? I have the students tell me what they think would happen and it would look like if they used 1/4 of a straw for pieces for the icosahedron and 1/2 of a straw sized pieces for the stellations (or 1/2 sized for icosahedron and whole straw pieces for the stellations).   Then I have them make it!

This actually ends up looking pretty cool! I don’t have any pictures of this off-hand, but I’ll be sure to add some later one when I do this project with my students this year. All the pictures provided are from May 2013…it took me a while to write the posts for the project! Yikes!

I hope you enjoy the project!

20 Pointed Star {Stellations} Part Five

This post is part of my Stellated Icosahedron Straw Project. See part one ,  part two,  part three  and part four first.

Did you make it through part four? I know that was LONG! The next part is much faster and also know that once you tell the students how to do the next part one time, every thing  is pretty much on auto pilot other than cutting additional string and fixing problems.

Today’s post is about the stellations, which are the points of the 20 pointed star. Let’s get started!

Step One: Cut off any left over ribbon from the icosahedron. You’ll want to change colors! Tie on your new color at any vertex.
SDC19560

Step Two: Add two straws to the new ribbon. Fold them down to create a triangle when attaching (by wrapping) to an adjacent vertex. Then feed it back up that same straw so it comes out the top.
SDC19561

Step Three: Add one straw and bring it down to attach it to the icosahedron! Notice how the point covers one face. It creates a tetrahedron (or you can call it a pyramid) for the point.
SDC19562

That’s one point! Only 19 more to go! Repeat steps 1 through 3 all around the icosahedron. As they get closer to finishing, students may notice that they may need feed their ribbon through other straws to get to faces that need a point on it. They can either feed it through to get to it or cut the string and reattached on the vertex of the remaining face.

Here are some pictures that show steps 1 – 3 repeated to create the other points:

Finished:

SDC19586

And you can hang it from the ceiling or they can take it home:

Some students finish VERY fast, others take three days to finish the points.  I usually let them make another if time permits, but I usually have them do a variation! I’ll explain what I mean in the next post!

20 Pointed Star {Icosahedron} Part Four

This post is part of my Stellated Icosahedron Straw Project. See part one ,  part two, and part three first.

In this post, I’m going to show you how to make the center of the 20 pointed star. It’s a 20 sided figure (Icosahedron). Beware that there are lots of pictures!
SDC19557To start, know that you should use only one color on this part. The 20 pointed star looks best if the icosahedron is all one color and the stellations are another.

Let’s get started!

Step 1: Take your long strand of ribbon and place five straws (note that I’m referring to the half straw pieces when I say straw!)
SDC19509

Step 2: Tie it together to make a pentagon. Note: Make sure every time you tie it, it’s a double or triple knot and is very tied well. DO NOT DO THIS FOR THE STUDENTS! Students will ask you to tie it for them, DON’T! Make them figure it out and be independent. Plus, you’ll go crazy and waste bunches of time if you have to tie it for every student.  Another note: leave a tiny bit of wiggle room in the pentagon, you don’t want the pentagon to be stiff. It should wiggle (a little) with ease!
SDC19507
SDC19510

Step Three: Cut off the pentagon from the ribbon and repeat step two but don’t cut the second pentagon from the ribbon this time.
SDC19511

Step Four: Pre-build the next figure (steps are below) and show the students that we are transforming the two pentagons to look like the next figure. I usually place it on my wrist and say it looks like a giant bracelet. I try to have them see the patterns and have them give me the next steps with out telling them, this helps them visual the next step because the next step is the hardest. Doing this makes it easier for the students to visualize the next step in their head. To help guide them, I sometimes put the two pentagons in the air with one a little above the other and have them imagine how to make it look like the prebuilt figure.
SDC19512

Step Five: Put a straw on the ribbon and bring it all the way down to the pentagon. You will then attach the other side of this straw to the other pentagon, which connects the two pentagons. To attach them, you don’t have to tie a knot each time (that’s very time consuming). Instead you can wrap the ribbon around each vertex, if you do this method instead of a knot, make sure to wrap it tightly and twice (that’s what I do!). You’ll need to keep one hand on it so it doesn’t come undone at first, but once you start the following step, then there is no need to hold it any more because the next step keeps it together.
SDC19515

SDC19516

SDC19517

Note: Make sure that you are wrapping the ribbon around the ribbon, not the straw:
SDC19518

Step six: The next couple of steps are very similar. Place another straw on the ribbon, bring it down to the pentagon, then connect it back to the other pentagon. This creates a triangle connecting the two pentagons.
SDC19522

SDC19523

Step Seven: Place another straw on the ribbon, bring it all the way down to the pentagon and connect it to the other pentagon. Notice how the pentagons start to become tighter each time. This is why we left wiggle room in the pentagons.
SDC19524

Step Eight: Place another straw on the ribbon, bring it down to the pentagon, and attach it to the other pentagon. Notice how the pentagons are even tighter now. At this point, we need to make it ‘pop up’ and be more three dimensional.
SDC19526

SDC19527

SDC19528

SDC19529

Notice: the two pentagons are basically on top of one another and the individual straws we added are starting to zig zag between the two pentagons.

Step Nine: Keep adding one straw at a time and finish ‘zig-zag’ around the two pentagons.
SDC19530

SDC19531

SDC19532

SDC19533
Ta-Da! You made it all the way around. That was the hardest part and usually ends the second day of the project. From here on out, it’s easy! :)

What we have so far is what I like to describe as a large bracelet. I usually stick my arm through it two show the students where the two pentagons went to in the project. To finish the icosahedron, we have to fill in these two pentagons.

Step Ten: Add TWO straws to the ribbon. Attach the ribbon to an adjacent vertex of the same pentagon:

SDC19535

SDC19536

Step Eleven: We want to use the triangle that those two straws created to help fill in the pentagon. To do this we need the ribbon to be at another vertex. Feed the ribbon throw the edge/straw to get to the next vertex:
SDC19537

SDC19538

Step Twelve: Add a straw, and attach that straw to the triangle.
SDC19539
I turned over the project to make it a little easier to work with:
SDC19540
SDC19542

Step Thirteen: Add another straw (which will start at the top of the triangle) and bring it down to the pentagon.
SDC19543

Step Fourteen: Only one more straw is needed to fill in the pentagon! Before you add that last straw, feed the ribbon through to get to the next vertex of the pentagon:
SDC19544

In this picture, I’m adding more ribbon by just tying two ends together, but you can see the completely filled in pentagon in the background!
SDC19545
Five straws go from each vertex to meet at one point to fill in the pentagon. No more hole on that side! But now you have to turn it over and do the same thing on the other side.

Repeat Steps 10 through 14 to fill in the other pentagon. You’ll notice that you will need the ribbon to be on the opposite side of the project. You can either tie a knot, cut if off, and reattach it to the other side OR you can feed the ribbon through the straw to get to the other side:
SDC19547

Pictures showing Steps 10 through 14 repeated:
SDC19548

SDC19549

SDC19550

SDC19551

SDC19552

SDC19553

Wahoo! A completed icosahedron! :) At this point, I’m usually in the middle of day three and show the students how to create the points. Some figure it out on their own though! Make sure to tie off the ribbon you are working on and cut if off. You’ll reattach a new color ribbon for the points.

As a side note, I want everyone to know that I have mastered typing long blog posts while covered in dogs. Yes, covered in dogs:

20 Pointed Star {Getting Started} Part Three

This post is part of my 20 pointed star project series. See my part one and two. The first day of the project is usually just setting up and passing out materials. If you have longer than a 50 minute class, then you would probably have time to start the next phase.

To Get Started:

Give each student a zip lock bag and have them put their name on their zip lock bag.  The large box of straws from Sams already come separated into smaller bags, so pass out one bag to each group. Each student needs to count out 45 straws and take the wrappers of the straws.  This makes a mess, so make sure to have extra trash bags handy.

SDC19584

As students work on separating the wrappers from the straws, use this time to start calling one group at a time to pick out their first ribbon color. If you stretch your arm out wide, that’s how long I usually give for each student’s first piece of string. I know it may seem like a lot, but trust me it goes quick! Luckily, there is plenty of ribbon on each spool. The amount of ribbon I have here is a little excessive because I’ve been building up my stash over the past few years. I think I started the first year with 6 spools of ribbon. It was plenty for all four of my classes (approximately 120 students). The project takes multiple days, so just keep an eye on your stash and determine yourself if you need to get more ribbon later.
SDC19583

90 straw pieces are needed, but we cut the straws in half so that the projects aren’t so huge! After they take off the wrappers, have them cut the straws in half. Make sure you take time to stress to the students that every piece needs to be the same size! Talk to them about strategies of making sure straws are the same size. For example, fold one in half to get the exact middle point. Use that one as a template to cut each of the other straws. Some will try to cut more than one straw at a time. For your sanity, put a limit on how many they can cut at a time. They will start cutting huge handfuls at a time. Straws go everywhere AND they end up being cut the wrong size. It’s okay for them to take their time on cutting the straws, just stress that each should be as close as possible to the same size! This process will take the students the rest of the class period. When they finish, all of their straws should be placed in their ziplock bag along with their strand of ribbon ready to start building the next day!
SDC19581

Keep in mind that students need time for clean up and gathering up all their materials. I usually start the clean up process about 7 minutes before the bell rings, maybe a little more on the first day because of all the wrapper pieces that I have to ask students to pick up off the floor! :)

20 Pointed Star Project {Materials & Organization Tips} Part Two

This post is part of my Stellated Icosahedron Project. See the first post here!

One thing I LOVE about this project is that the materials are relatively cheap, specially considering that it covers EVERY student’s project!  The first couple years I spent about $40 out of my own pocket to cover the project, but over the years I learned to ask students/parents for donations or to bring a spool of ribbon.

SDC19587
Materials Needed:

1. One Large Box of Straws from SAMS! (a little less than $20)

SDC19585
SDC19584If you have students bring their own straws, make sure they are clear and not bendy straws.

2. Ribbon in variety of colors (about $3 a spool but ask for students to bring it in a head of time for donations!) These can be found usually in Walmart in limited colors, but I usually get mine at party city because Walmart is hit or miss with stocking them:
SDC19508

3. Scissors

4. Ziplock Bags (one for each student, use permanent marker to put their name on the bags!)

5. Boxes for storing ziplock bags (one box per class)

Organization tips

This is a HUGE project that will consume your classroom for at least a week. Want to keep your sanity? Use these tips:

1. Use an upside down chair to help store ribbon and pull the ribbon off the spool. If the spool is on the chair leg, it makes is super easy to pull the ribbon and cut! Trust me, you’ll be cutting lots of ribbon the first couple days and will want to make this go much easier! Put the ribbon you are cutting on top. If you are cutting ribbon that has some other ribbon stacked on top, then pulling the ribbon on the bottom will also turn the ribbon on top, which tangles the ribbon. Trust me, I learned the hard way and I’m hard headed, so it took me a couple of times to learn this. :)

SDC19583

2. Use ziplock backs to store the straws. Use a different box for each class! It makes it much easier to pass out materials at the start of each class if it’s organized neatly.

SDC19581

3. As the projects get bigger and no longer fit in the zip lock bag, hang them on a ribbon in your classroom. Keep them off the floor!
SDC19580

4. When you hang them up, make sure students have their name on them. I have them use a small piece of paper and tape it around a straw!
SDC19579

5. Do you best to make sure the strings don’t get tangled!

Stellated Icosahedron Project {20 Pointed Star Project} Part One

Every year I do this fun end of year project with my students. They love it, I love it, and it saves my sanity after testing.  Seriously, the first day or two is rough because the students don’t want to listen to instructions, but once they get the hang of the project, they pretty much go on auto pilot. It’s scary how quiet they get as they get as they work on the points of the star.  With the end of the 3rd quarter this week, I figured it’s the perfect time to share this project!  I’m sure I’m not the only one thinking about all the things that have to happen as the year comes to a close!

SDC19587

Overall, the project will take the students about a week to complete because of the instruction and organization needed. It takes a lot less time if teaching someone one on one!  This project is perfect for 7th, 8th, or high school math classrooms. It is super fun and perfect for the week or two after testing that you end up not having much to do! Plus, we do talk about math concepts while we complete the project.

Example topics to cover:

  • Two-Dimensional vs Three-Dimensional
  • Regular Shapes
  • Review two-dimensional shapes and introduce names of three-dimensional solids with regular faces (called platonic solids)
  • Area (each face), Surface Area, Volume
  • Vocabulary: Edge, vertex, face
  • Euler’s Formula
  • Platonic Solids and this funny video and this video
  • Stellations

I usually create a handout/packet for them to complete as we build the stellated icosahedron to review topics previously taught.

I’m going to divide the project into a couple of different posts to create a little mini series. Plus, it’s too much to cover in one post. Here are the topics:

1. Materials and Organization Tips

2. Getting Started

3. Icosahedron (inside part)

4. Stellations (points)

5. Variations/Extensions

I hope you’ll join me on my first mini series!

Zombie Attack!

Help, the zombies are coming!  Okay, so there aren’t really zombies coming, but I sure feel like a zombie right about now! There is so much to do and I am wiped out! Which is my reason for the lack of blog posts in the last week.  I’m doing everything I can to stay a float right now. Do y’all ever feel drained?

Well, last night I got in a better mood by hanging out at one of my favorite places (Panera Bread! Love that place!) and gave myself a chance to just create what ever my little heart-felt like at the moment. I was inspired by Sarah Hagan and her zombie game. She told me a little about it on my post about a different powerpoint game.

Both of these games use special animations called triggers. These triggers (along with hyperlinks) allow you to create some pretty awesome games. It allows the animations to take place on a specific objects allowing you to choose the order of the animations while presenting rather than general animations that happen in specific order no matter what! As a bonus, if you click an object to perform an animation then move forward a slide then go back to the slide with the animation, the slide will keep the animation where you left off!  This allows you to keep score on one slide, move to a question slide, move to an answer slide, then back to the score slide to add points (or take away brains in this game).

Here are some pictures:

Zombie Attack

Zombie Attack

Each zombie (one for each group) has a stash brains. This is the score board:
Zombie Attack
The zombie’s stash is the two rows directly below the zombie.  Notice the large brain and grave/hand images. These are the icons that will take you to the question pages or back to the score board.

We all know zombies aren’t friendly, so that is where the questions come into play. Questions are listed here:

Zombie Attack

My students had to do the even problems on a particular page from the textbook, so that is why it has #2 for question 1:
Zombie Attack

If a zombie(group of students) answer the question correctly, then they get to attack another zombie who then loses a brain from their stash (the brain disappears when you click on it). If the attacked group also had the correct answer on their dry erase board then they can choose to shield or block the attack in order to not lose the brain, but if then they also forfeit their chance to attack someone else. Groups that got the problem wrong do not get to attack or shield if someone chooses to attack them!

I also have the answers in the Powerpoint so they can check their work easily:
Zombie Attack

The students were VERY competitive, but they were also very sweet. When a group got down to their last brain, other groups didn’t want to attack the group with only one brain left. So sweet!

As a side note, if you plan on creating a powerpoint game using triggers, this feature isn’t available in keynote or powerpoint for mac…trust me, I’ve tried EVERYTHING to get it to work on a mac, but it won’t work on the mac, only pc.

Death by Subtraction {Solving Equations with Variables on Both Sides}

Do you ever see something and just get tickled down to your core? While grading a pop quiz {one that I was very much dreading to grade}, I found this:

Untitled

I know it’s not a very ‘happy’ picture, but it did make my heart smile to see his understanding of the concepts!  I was truly dreading grading this pop quiz, but my students did REALLY well. This is the first time that I have EVER taught my regular 8th grade class {not algebra} to solve equations with variables on both sides. Students struggled, I mean STRUGGLED, with chapter 1 which was solving two-step equations with integers.  I worked in equations every chance I get, but it is sometimes difficult to know whether it’s making a difference.  Overall, the students rocked this pop quiz. On top of the excitement, I get this gem of a picture!
