Go Fly A Kite

My colleague and friend, Danyelle, has done this kite construction project for a number of years during summer school. She first saw it at a conference many years ago. We decided to try it last year during the school year and then the pandemic closed school and we didn’t get to do it. When the time came to complete the project this year, we realized all of the information Danyelle had for the project was destroyed in our black mold fiasco. We did a Google search for tetrahedral kites and realized there are many resources for similar projects out there. I’m sharing what we came up with, but you can do your own Google search and find many additional resources too.

For this project, students build a tetrahedral kite, reflecting on surface are and volume as they create it. We also added some Trig in at the end measuring the height of the kite using our clinometers. I found another resource that did the same thing. Great minds!

The day we flew our kites was super crazy windy. Some of our kites didn’t hold up as well as we would have liked and only a few were able to stay in the air. The kids had a lot of fun and we had some great discussions about kite construction and the best place to tie the string. All productive conversation with critical thinking.

Here are the resources we compiled from memory and from resources we found.

Don’t forget to do a Google search for Geometric Kite or Tetrahedral Kite to find many other resources. This was a lot of fun and we need fun with the year we’ve had!

Enjoy

Circle Theorem Explorations

The circle theorems unit is one where I question when we will use it but see the value in helping students explore and think. One way I like to do this is by having them explore the theorems and record what they notice.

I use Geogebra for the explorations. Some of these are ones I have made and others are ones I have found made by others. I love Geogebra for explorations because you can interact with the images and see what happens when you make the circle bigger or change the angle measure.

If you are wanting to use more critical thinking for the circle theorems unit, I hope you give these a try.

I hope you find these helpful. Check back soon for more circle theorem activities.

Surface Area and Volume – all the goods

As promised, here is a compilation of all my area, surface are and volume projects and activities.

Surface Area

Volume & Spheres

Since I’m teacher a much lower group this year, I wanted application problems for them but with a little less challenge so they could be successful. Here are the two I have created for them so far. Working with a partner, they have been able to use the calculator and find the answers.

Quadrilateral InfoNotes

When we were fully remote and then hybrid, I wanted to give my students options in their learning and I wanted one of the learning options to be visual. When I set up my Canvas for a lesson, I have a table where the left side is read and the right side is watch. On the left side I include these infonotes (yes, I made that up but it’s my blog so I can, LOL) and some hand written notes. On the watch side I include videos, some made by me and some that I have found. Some students (I’m one of those students) don’t like to watch videos, but some students don’t understand without the video. This gives them the option to learn with a style that is best for them.

Now that we are back in person, I still post these options. They can learn from me, or they can chose to read or watch videos.

I’ve included my infonotes for the quadrilateral unit. I have them for every unit in Geometry so I’ll need to get around to posting those :-).

I also used these two activities I have previously posted as an exploration for interior and exterior angles.

I modified these Desmos activities I found to use with this unit. They are wonderful as is, but some of my lower functioning kiddos struggle with explaining so we have a conversation instead of typing. I posted the original activities below so it also gives credit to the author. One day soon (as soon as my dissertation is done) I will be creating in Desmos!!!

A few weeks ago I shared the Exit Tickets I created for this unit. Click here to see that post.

And last but not least, I have an Escape Room that I use as a review for Quadrilaterals. If you want to see your students submissions, just make your own Google Form and have students use yours instead of the one on the escape room site.

You should be set to teach Quadrilaterals. I hope you find something you can use.

Quadrilateral Comics

This idea has been rolling around in my head, especially when I’m on the elliptical working out, so I’m excited to try it out with students.

The idea behind this activity is to get students to think about the properties of quadrilaterals. There are so many rules to remember and there isn’t a ton of application. I know what you are thinking, then why are we teaching it? Well, it’s still one of our state standards and it’s on the ACT/SAT test, and there is some great logical thinking that happens during this unit.

They will create a comic with two quadrilaterals. In the comic, they must work at least 3 properties for each quadrilateral into the story. The characters are the quadrilaterals themselves.

I wanted this to be 8.5 x 11 so we can put it in iBooks or Kindle when we are finished. Wait, you didn’t know you could do that? Never fear, the instructions are listed below.

I created my own template but I also share others that I have altered and some that aren’t altered but you can use if you don’t care about making it an actual book.

I will begin this with students tomorrow so I will update this with students samples once I have them. Here is an example comic I made to show students.

I have also created the activity sheet that I will post in Canvas. I plan to introduce this after our Geogebra Exploration and then give them the entire unit to complete it.

Once your comic completed, you can go to File-Download as PDF. I move this to my GoogleDrive. On you phone or iPad, go to the file in Drive and click the 3 dots in the corner. Click open in and scroll to the end of your apps where is says more. Once you select more, Kindle and iBooks are both an option. It won’t work with Kindle if the file is too big.

I have some additional tips and tricks for creating comics on infinitelyteaching.com. Check out that post for more ideas.

Let me know if you use this idea. I love to see the creations from other classrooms.

Similarity Exit Tickets

As promised last week, here are some exit tickets that you can use with a Similarity Unit in Geometry. Just a reminder of how I use these. I give feedback on each submission and have students work on them until they are correct. I love doing this with the comment feature in Google Slides. In Canvas, I am using the Google Assignments LTI so it looks just like Google Classroom.

Now, you might not want my Bitmoji on your slides. I mean, she’s cute, but I get it! You can go to view-master and change the Bitmoji there. I changed my jacket color for each day. One student told me he was excited each day during the lesson to see what color the jacket would be but slightly less excited about the math. 😂 Whatever gets them there!

I hope you find these useful. I share them to save you some time! I really like exit tickets because it helps me fix misconceptions quickly.

Exit Tickets for Triangles Unit

It’s nice when you find an activity that you can just USE. If you are getting ready to teach or review triangle congruence, hopefully these exit tickets will be helpful.

I give these the same day I teach a new lesson. Students get feedback from me until they have correct answers. It has worked very well during our hybrid schedule but I plan to keep doing it when we go back in person.

These slides are interactive so you will want to make a copy for each student. You can edit the content by going to view-Master. I create it there so the static parts don’t move.

Each one is set to template. If you would like to keep the activity, just select the get template button in the top right corner.

Corresponding Congruent Parts

Isosceles and Equilateral Triangle Theorems

Triangle Sum and Exterior Angle Theorems

Triangle Congruence Theorems

Triangle Congruence Proofs

I hope you find these useful. I am working on a set for Similarity. I’ll post them soon!

Road Kill Kafe goes Remote

Well that sounds like a movie title.

I wanted to share with you a quick update to Road Kill Kafe that I use in my Geometry class to discover congruent triangles. It was shared with me by my friend Craig Klement (@CraigKlement) and you can read about all of my Triangle Congruence activities here.

We are hybrid this year and it usually takes 2 days to complete the activity. That’s 4 class days with both classes and we simply didn’t have the time to do that.

So… I turned it into a digital activity. It worked out ok. I did model some skills for them regarding the drawing tools in Google Slides and that made things go more smoothly. I also pasted a reference segment so we could make sure our side lengths were what they should be.

Here are some images of our completed triangles.

If this is your original activity, let me know! I would love to give proper credit. If you want to try Road Kill Kafe goes Remote, just click on the links below. The first one is the activity to send to students. Make a copy for EACH student. The second one is the collaborative slide with the reference segments for students to paste their completed triangles. Make sure you set it so EVERYONE has access to the same slide.

Geometry Flipbook

I am not a paperless classroom. As I say in my book, use technology if

  1. it makes your job easier
  2. it makes the learning better for students.

So why a digital flipbook? Well, it’s actually not just one reason.

  1. We have to go remote this fall, not because of Covid but because we have “spores” in our building that required them to close the building, throw away all of our porous material (i.e. books, saved foldables and student work, 20 years of personal books and memories).
  2. I know some of my students won’t have paper at home to make a foldable while remote.
  3. Umm… my foldables are all gone (see reason 1). They were thrown away 😦 If they had been digital, it would still have them.
  4. I saw this idea in a TikTok by @adungan and knew this was my solution.

I recreated one of our foldables that was destroyed. I plan, with all of my digital lessons, to have students take pictures of their work and paste it in the foldable (or notes or practice, etc). I don’t want them to have to draw every image, but I also don’t want phantom floating notes so when they look at them there is no image or problem to reference.

I made a little tutorial that I am posting in Canvas/Google Classroom (this has been another huge debacle) to help them create a good scan and clip their images. (This is a Slides Mania notebook template)

Here is the foldable as the students will see it. I will put it in Google Classroom and set it to make a copy.

If you are putting this in Canvas, make sure you force a copy. Here is a gif from Jake Miller (@JakeMillerTech) to help you with that.

And here is a completed copy with student work snipped and uploaded into the document.

If you want the template, here is a link. You can also snag a copy on Slides Mania in the By EDU for EDU section. Paula is AMAZING and creates great stuff. She is also kind enough to share what others teachers create.

Now, if you are adventurous and want to make your own, I created a tutorial posted on InfinitelyTeaching. You will also find a 6 topic template posted there ;-).

If you use this, please let me know on Twitter. I LOVE to see what people create. Tag me @MandiTolenEDU and use #MMNS and #infinitelyteaching.
