Students read it and try to think of possible punch lines.
Just before the bell rings at the end of the day, kids share punch lines they came up with, and then I reveal the answer. It's a fun way to end the day on a positive note. I used to hear choruses of these questions throughout the day until I came up with a solution. I made a sign for each activity or subject, including math, reading, and lunch. I then used construction paper to make analog and digital clocks that display the times these activities begin.
