Regardless of how many times I play this joke, students fall for it year after year.
This is a test about following directions. It is set up very seriously, so that students genuinely believe they are being assessed on their ability to follow directions. It is a timed test, to ensure that your students not only fall for it, but fall for it in the most hilarious ways possible.
Here's how it works:
-Tell your students that you need to assess them (I like to throw in words like 'board-wide initiative')
-Hand out the test
-The instructions state (very clearly) that students are to read over the entire test before beginning (none of them will, especially as the test is timed)
-The questions are a mixture of serious sounding ones (like very simple algebra or order of operations questions) and completely ridiculous ones (sketch the back of the head of the person in front of you)
-The final question congratulates them on reading all of the questions before beginning and instructs them to not complete the test at all, but rather sit back and have a chuckle while everyone else does
