For an Icebreaker activity in my classes on the first day of school, I am using an app called Goose Chase to conduct a scavenger hunt. The app is free and is available on both the App Store and Google Play. In the online dashboard the teacher creates "Missions" and assign them different point values. The free version of the game allows 10 participants at a time so my students will work in groups.
When beginning the scavenger hunt, students will search for the game name I will give them and put in the password. You don't have to assign a password but I did for security purposes. When participants begin the game they will see a list of Missions, each assigned a point value. Students have to submit a picture to receive points for the task. I am using the activity to familiarize students with the classroom (i.e. eye wash station) as well as to help them get to know each other (i.e. find someone who has an after school job).
The teacher will control the game beginning and end in the desktop dashboard and can also see all student submissions. I'm not sure if your submissions are saved if you use the same game multiple times so I copied my game in the "My Games" tab and renamed them by class period. The game also ranks the participants by the number of points received. I think this app could also be a fun way to conduct a review for a quiz or test. One possible fun application is for math problems where students would submit pictures of the solution that include showing your work. Please share any ideas or experiences you have in the comments below.
