From the text: When confronted with a challenging problem, many solvers may at first think that not enough information has been provided. If, however, they suspect that the problem is solvable, this feeling typically influences them to persevere as well as monitor and reflect on their efforts. We present four nonroutine tasks that we have posed to mathematics teachers and students to engage them in problem analysis and strategic behavior. Included with two of the tasks are descriptions of some common reactions and solution strategies. These tasks address NCTM's Standards and the Common Core Standards for Mathematical Practice. Readers are encouraged to solve the problems themselves to better appreciate the solutions and hints given.
