In need of a problem solving day for students? This activity is called a Math Lab for no other reason but students using the time and tools they know to problem solve. This problem was all about buses and figuring out how many buses are needed for a Six Flags trip.
It can be used from grades 6 and up and can be solved with multiple approaches. Try it with your younger students and you will be surprised by the different strategies they use. Let me know how it went for you.
