Broken Calculator

The Broken Calculator helps students develop computational fluency by solving problems with a "broken" calculator. For example, a baker packs 315 buns into boxes of 8. How many boxes will the baker need? The division key is broken! Students must find ways to solve the problem, evaluate the solutions, and explain their reasoning.
