Using QR Codes with Equations of Lines
I think QR Codes can be very valuable in a high school classroom. So, I decided to try creating my own activity using QR Codes. For this first activity, I am going to have students scan a QR Code when they would like to check the answers to the task card. I realize that students could just scan the code and get the answers, but they could also just turn to the back of their book to get the answers too! I am hoping that the novelty of using the iPad/iPhone/other mobile device will be enough to get them to try to do the problem first!
I know nothing about QR Codes really, except that you see them everywhere, and I know I have an app for that! So, I am learning about how to use them in the classroom. So far, I have discovered that I can embed text, video, or a url into the QR Code. What I am struggling with right now is how I can give students answers to questions that need mathematical notation. For example, I know I could type sqrt 2 to mean the square root of 2, but it's not good math notation, and I want my students to use good notation!
So, I am trying to figure out where I can store my QR Codes so students can get them. I am open to any suggestions that you might have - leave them in the comments section.
Here are what two of my task cards look like.
I am really excited about this new method of helping students learn with technology!
