You are so excited to use the Sphero to teach your students angles, coding, and problem-solving. Unfortunately, the Sphero is locked in Mr. Mullaney's office. He is away at a professional wiffleball tryout. Mr. Mullaney's office does not have a conventional lock-and-key. Instead, there are five locks on his door. You have to crack all five locks to liberate the Sphero and make your next class awesome. Hurry though, class starts in 45 minutes and the clock is ticking!
