QR Code Scavenger Hunt

Test review days.  You can’t live with them, you can’t live without them.

In an effort to make a recent geometry test review day a little more interesting, I decided to try an idea I had heard from another teacher:  making a QR code scavenger hunt.  I was really pleased with the way it went.  Here is what I did:

1.  I created a set of 10 geometry problems and made each one a separate Google drawing (most of them had diagrams).

2.  I used a free online QR code generator to generate a QR code for each question.  I printed out these QR codes and posted them in semi-sneaky locations around the school library.

3.  I paired up my class and created a Google form that

a) sent each pair to a different starting question

b) for each question, told the student where to look for the QR code

c) once they found the QR code, they scanned it and got the question.  Then, they had to input their answer into the Google form.  If they got it right, it told them where to look for the next code.  If they got it wrong, it told them to try again until they got it right.  The questions looped around until each pair had answered every question.

Things that I liked

1) It got the class up and moving.  I read an article a while back about how students need to move more during class, and I’ve been trying to think of ways to make that happen.

2. It fostered good team work.  One student was responsible for managing the form, the other for managing the QR scanner, and I saw a lot of conversations about answering the questions.

3. It left room for surprises.  I put one QR code on the inside of a wide window sill, and when my students started the scavenger hunt, a girl had sat down in the window to read with her back to QR code.  One pair found it eventually and tipped the rest off, but it definitely added a little twist to the morning!

I would definitely do that again.
