One way to play an April Fool's joke in the classroom is to create a fake pop quiz or assignment that seems challenging at first, but turns out to be a fun and lighthearted activity. You could also switch the classroom layout or rearrange the students' desks when they're not looking, creating a surprise when they enter the room. Another idea is to bring in a fake guest speaker or pretend that a class pet has gone missing, only to reveal the joke after a short period of time. Just be sure that the joke is harmless and won't cause any distress to the students. **

The tradition of playing April Fool's jokes is typically only observed on April 1st.
