ab: 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.
