After completing practice with finding the least common multiple, students will place the letter that matches their answer in a puzzle to answer the riddle: "What happened to the leopard who took a bath three times a day?"
Thank you! I usually only assign my riddle worksheets when I know they can finish them during class. When I pass the worksheet out, I say "now if you figure out the answer to the riddle, don't tell." Also, requiring them to show their work, makes them do the problems even if they already know the answer.
