When you look back on your school days, you probably remember those who taught you your ABCs and, later on, more complex and tedious math equations. While some teachers may have rightfully earned a positive reputation, others deserved some bad press, right? However, this profession shouldn’t be taken for granted, especially considering that many teachers have to work long hours and deal with rowdy students. Some witty educators have hung signs in their classrooms as a last resort to restore order and implement innovative learning techniques. From a questionable way of telling students to practice with their instruments to a SpongeBob meme that encourages language learning, take a look at these original classroom signs.
