Photomath is a math app that lets students focus the camera of their phone onto any printed math problem. Once focused Photomath shows the student step by step all of the work and answer to the math problem.
There are good uses for the math app of course as well. It is great for us as teachers when we need an answer quickly or want to check our work. This also applies to the students. If used properly, it can be a great resource because they can check their work in a moments notice step by step without having to come ask you question on every single problem (yeah, we all have students that do that!)
Why write about how to cheat?
So why am I writing an article about how students are cheating in your class? Because this math app and others like it can be used in great ways too if controlled. GeometryCoach.com is all about saving teachers time and frustration. This math app can do both for you! The best thing you can do is let your students know you know about this math app, you know they are using it, and you can tell when they are using it. Get on the same page as your students. Show them ways they can use this math app to help them better understand math.
Another way to combat this is to use Google Classroom for your assignments. Here is our eCourse on 'How to Setup and Use Google Classroom and Google Forms to Teach Geometry.' This course also come with a Certificate of Completion to use for your artifacts and CEU's.
