Running in Circles

Today we discussed all things circles. We talked about the radius, diameter, circumference, and angles. Thanks to technology, we had a whole new way of learning about it!

A couple weeks ago, one of our blogging buddies, Mrs. Hembree wrote a post highlighting the changes to their library. As part of that post, she used a Microsoft program called Photosynth to create a panoramic image of their library. That sparked an idea!

Using an iPhone app called 360 Panorama, we were able to create our own panoramic images to help us learn all about circles.

In our first panoramas, we find the radius. You’ll be able to see yarn stretching from the center of our classroom to the front of the room. The radius is a line segment extending from the center of a circle out to the edge of the circle. To navigate through the picture, just click and hold down on the mouse, then move it from left to right or right to left!

If these have trouble loading on your computer, you can also access our panoramas by clicking here. You can load any of the panoramas by simply clicking on them.

Our next panoramas show us the diameter. The diameter of a circle is a line segment that stretches from one side of the circle to the other. The diameter has to pass through the middle point of the circle. In the image, you’ll be able to see yarn stretching across our image to represent our diameter.

The next group of panoramas show the circumference of our circle. The circumference is the distance around a circle. Look for a black piece of yarn stretching all the way around our classroom to mark our circumference.

Our fourth group of panoramas represent the many angles within a circle. We often hear the term of someone doing a 360 in basketball, skateboarding, or snowboarding. That refers to 360 degrees, or 360° which represents the distance all the way around a circle. That means that half way around a circle would be 180°. Start with 0° in the front of the room. Work your way around clockwise until you end up back at 360°. You’ll be able to see the many angles along the way! If you can’t see an angle well, you can zoom in by hitting the plus button on the left side of the panorama or by using the scroll bar on your mouse.

For our final panorama, we decided just to have a little bit of fun. Students were able to pose however they wanted as long as they were still along the circumference.

*What else do you think we could use a panorama for to help us learn?*

*What do you think the length of our radius and diameter might be?*

    Dear Mr. Avery’s Class,
    I’m so glad a post we made on Photosynth could spark a new idea you could use! I wanted to view your videos, but they aren’t loading for some reason only my computer knows!
    However, I think whenever you use panorama or other visual ways to explain something, it helps the learners who are visual learners like me! I have to SEE something to understand it and even better if I MAKE something, it helps with my kinesthic side.
    Well done, I wonder what video you will make next? Have you decided?

      Hi Mrs. Hembree,

      So glad you found our new post so quickly. I was going to leave you a comment that we had mentioned you in our most recent post!

      These do seem to be loading a bit slowly. I had no trouble on my laptop but then on another school laptop they weren’t loading at all.

      I added a link onto the post so that if they don’t load, you can view my profile on Occipital and see them from there. Hopefully it’s just a matter of the servers being slow today and they’ll be up and running in no time!

      Mr. Avery

        Dear Mr. Avery,
        I found out about your post because you ping backed on my post! It’s that great how the connections work?
        I’m sorry to not be able to see the movies. I haven’t been able to load them anywhere, but I imagine them to be great!

    Dear Mr. Avery,
    The radius of our class room is 15 feet. Our circumference is 30 feet. This was a super cool activity. I really hope we do it again!

  3. Fiona P. says:

    Dear Mr. Avery,

    The answer to your question is the radius is 15 ft and the diameter is 30 ft.


  4. Alyxandra says:

    Dear Mr. Avery,

    I think the diameter of the class is 30ft and the radius is 15ft! I got the app 360 Panorama because of you! :) Thank you for showing me. My parents think it is really cool! See you tomorrow at school.


  5. Kelsea R. says:

    Dear Mr. Avery,

    To answer your question about the length of the radius and diameter, I think the radius distance is 15 ft and the distance of the diameter is 60 ft.

    It was really fun making the videos.


  6. Tessa P. says:

    Dear Mr. Avery,

    My answer to our bonus question/comment is that I think the radius 14 feet and the diameter is 28 feet.

    Your student,

  7. Taite B. says:

    Dear Mr. Avery,

    Another way to use a panorama to help us is how to measure different angles. I think the radius of our class is 15 ft. and I think the diameter is about 30 feet. Hope I did well!:)

    Hello Mr. Avery,

    I think that the radius is about 15 feet and the diameter could be 30 feet.

    Aloha Mr. Avery’s Class,
    Wow! I love your work! I can just envision using this same idea outside of the classroom. This brings so many ideas to mind.
    I am enjoying every post and looking forward to many more.
    A hui hou,
    Mrs. Jacobs

    Dear Mr.Avery,

    The radius of our classroom would be probably about 15 feet and the diameter would probably be 30ft.

    Dear Mr. Avery,

    I know how we did that awesome activity to work with circles! When we were done you said if we could go on here, on the blog, to this post and comment on what you think the diameter (a line segment going from one end of the circle to the other) and the radius (a line from the center of the circle to the edge of the circle). Well, I think the diameter of the room is around 48 feet and the radius, 24 feet. Maybe to find out to see around how many feet the radius and diameter might be we could count the amount of tiles onn the floor? :mrgreen:

    From you student,
    Jennifer W.

  13. Ed S. says:

    Dear Mr. Avery,

    I think the radius is 13 feet and the diameter is 26 feet. Also, a panorama could also help us learn 3 dimensional shapes by going around them and seeing their faces, vertices, and edges.

    Dear Mr. Avery and class,

    We loved this idea! It was very exciting to get a peek inside your classroom. This post gave us a good idea for how we can use technology to help with our classroom learning. We have not heard of the 360 Panorama app before. Most of us want to download the app for ourselves. We think the yarn was a good idea to measure the circle. We think it was great that the students were a part of the circle and angles. It’s much more interesting than just on paper.

    Our class last year used a website called 360 Cities. Click here for an example that we used of the Grand Canyon. We think this would be a good example of when you need a panoramic image!

    Tori would like to see a panorama of outerspace. Jagger thinks a zoo panorama would be interesting. He could use it for creating a map. Nadia would like to take a panorama of a forest. David and Callie would like to take a 360 picture when they are under water.

    Thanks for sharing this marvelous idea with us!

    Dear everyone that wrote comments,

    I also agree that making the videos was fun. i didn’t have access to a computer to answer the bonus question but I would have.

    Sam R. :wink:

  16. Alyxandra H. says:

    Dear Mrs. Moore,

    I am so glad that you like our idea and are using it with your own class! Your students had a lot of great ideas on what to do with 360 Cities. I especially like David and Callie’s idea on taking a picture underwater, great thinking!


  17. Morgan M says:

    Dear Mr.Avery,

    This project was so cool! It made learning about circles so fun. I hope we do more projects like this one this year.

  18. Morgan M says:

    Dear Mr.Avery,

    I think that running in circles is one of the best posts yet. Even know my face was cut in half in one of them I still think it is really cool.

    • Alyxandra H says:

      Dear Morgan,

      I agree with you that this is a great post! And I’m sorry that your face was cut in half :lol: I got 360panorama on my iPad and its so cool! I’ve been trying new things all over my house.

    Hello Mr. Avery’s Class,

    This is great! I love the idea of using all these great technological tools (Photosynth and 360 panorama app) to apply them on mathematical problems in real life situations. I’m a student-teacher and I was talking to another friend in the education program and she wanted to make mathematics fun and interesting. This is a great idea.

    Thank you guys for such a great post.

    Dear Mr. Avery,

    I’m so frustrated. None of the videos show up! It’s just a puzzle piece with crossed out eyes.
