An Intro to Pythagorean Theorem

As I am beginning to create my online unit I am already learning a lot about different great tools. Firstly, I have to share my appreciation for Google. Before this class, I never really utilized all of its great features, like Google Drive, Google Docs, Chrome extensions, Google Classroom, and Google+ Communities. All of these applications have helped me progress in ECMP, but also in my other university classes as well

For my online unit, I am going to use the Grade 8 Math curriculum, specifically the outcome based on learning the Pythagorean Theorem. I chose this topic because there are so many different applications of this theorem so it will give me a chance to try out a lot of different tools, like Screencasting, Khan Academy, Youtube, and EduCreations which I heard about through a blog post by Amy, one of my classmates.

So far, I  have created my first assignment in Google Classroom. The assignment is to watch an intro. video to the Pythagorean Theorem, and then to complete a short comprehension worksheet to ensure the students watched the video. A few things I learned while creating this assignment was that Google Docs has an option to insert equations into your document; it will convert all of your variables, equation signs, and exponents into proper form! I am not sure if this is news to you readers but WOW was I ever amazed. As a Math major who is constantly googling different equations for help on assignments, I have gotten very used to using “^2” to represent a number being squared so actually being able to convert it to exponent form was very exciting. I have also learned about “making a copy” so all of my students can make a copy of the Google Doc assignments they receive and then simply reshare them with me to be marked. At first, I was worried how each student would separately edit their assignment until my co-op from my ECS 300 field experience showed me how he uses Google Docs for assignments with his students.

I have also created a Google+ community for the pretend parents of my pretend students. I think that when doing a unit completely online, especially with elementary students, it is important to include the parents. The parents can use their own Google account and access the community from any device with internet. I will use the community to post reminders about assignments, as well to communicate with the “parent” after any assignments or grades have been posted.

My next plan is to use EduCreations to create a lesson on actually applying the equation, a^2+b^2=c^2 (no “insert equation” option here). For the assessment after the lesson, I am going to research online tools for assessment. Although I could rave about Google Docs forever, I would still like know what other tools are out there for online assessment, especially for Math units.

Lastly, if you would like to join my Google+ Community or classroom to follow my progress please click here for the community, and you can join my classroom by logging into Google Classroom and entering the class code: pte2zq. Don’t feel obligated to join by any means just an option to those interested!

  1. Alex,
    You’re killing me 😜- it looks like I’m going to have to put some time into all things Google, and give it more than a skeptical try…a few more times. Thanks for breaking things down into some starting chunks for exploration😊.


  2. I absolutely love the Pythagorean Theorem. It’s so much fun and I think it’s one of the first formulas students get to learn. I like that you have a little worksheet for students to fill out so students can follow along in the video, students (will hopefully) pay more attention to the video this way! I also love Google Docs! They are amazing. I also think Google Classroom is a great resource to use.

    I enjoyed the video that you are using. I think it’s a fun way to introduce the concept. I would caution using a^2+b^2=c^2 for the Pythagorean Theorem all the time because I have found that students will then only think the hypotenuse will be ‘c’ and students will have trouble using other letters for the hypotenuse.

    Also, here is video that gives a quick visual representation of the Theorem:
    I think it’s a fun way to demonstrate to students the definition of the Theorem: The square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. You could show the video multiple times and have a class discussion on the meaning behind the Theorem.

    I know it’s a pretty popular online assessment tool, but Kahoot is always a nice way to see what students know and don’t know. It’s online and students can use phones/computers to put their answer. It would be more of an assessment that wasn’t for marks, but to see where students are at.

    Since we both love Google, Google Forms is a cool way of doing online assessment (T/F, multiple choice, exit notes, polls, etc.)
    I just tried it out for the online unit I’m doing and it was easy to use.

    I can’t wait to see what you do next! I love what you have so far!


  3. Hey Alex, thanks for the shout-out. 🙂 I’m glad that you are going to try Educreations – I think it’s a neat tool. I hope you find it useful in your unit plan. I’m looking forward to watching your first Educreations lesson!
