“Huck Finn” is subbing for math teachers who are away from class learning how to teach to the new Common Core standards. Finn worries that teachers will be told to require students to find multiple ways to solve the same problems, he writes in Out In Left Field.
There’s nothing wrong with finding multiple ways of solving problems. But in early grades, students find it more than a little frustrating to be told to find three ways of adding 17 + 69. Putting students in the position of not satisfying the teacher by producing a correct answer and showing how they got it unless they find multiple ways of doing it is a recipe for 1) disaster and 2) rote learning, the bugaboo of the purveyors of “find more than one way to solve it”.
If a student can do a proof or solve a problem correctly, he or she shouldn’t “also have to do 25 fingertip pushups,” Finn believes.
When my daughter had to do a “problem of the week” in pre-algebra, the last question always was: How do you know your answer is correct? She’d write: “I double-checked my answer,” leaving out the fact that she’d double-checked with her smart friends or her father, who majored in math at Stanford. I think students were supposed to say they’d solved the problem in multiple ways, but nobody was dumb enough to do the extra work.
