It's sometime hard to be able to get to all my students and give them individual one on one help, especially during review time. I find myself running from one end of the class to the other. So then I decided to attach a QR code on their sheet where they can use a smartphone or ipad with a QR app and scan it. It'll direct them to a google drive link where I have my answers written in step by step.
This way, not only do my students get to check their answers, but if they're stuck, they can look at how I solved the problems step by step. This ended up saving a lot of my time and my students time since they didn't have to wait around for me to come by and help them.
Though I must admit, it did take up maybe 10 minutes (oh no!) of my time to scan, upload my answers onto google drive and create a qr code for it. But in the end, it saved my time during class.
This was also beneficial for the students at home since if they were stuck, they were able to simply scan the qr code and be directed to step by step solutions.
How to create a QR code worksheet?
1) Scan answers and upload onto google drive
2) Share with Others (Make sure to copy and paste the link that allows "Anyone with the link can view"
3) Copy and paste link on QR code generator: http://goqr.me/#t=url
4) Download or copy QR code
5) Paste onto word document
Here's an example of what I have done with my grade 11 Functions class.
