Another in a long line of stories about how parents need to be taught the inefficient, non-standard methods for simple math, so they can help their children “understand” . And of course no such story would be complete without this trope of a quote:
“The important thing is explaining how you know what you know,” Timm told the class. That’s what he wants their kids to leave school with — a deeper understanding of math, beyond rote memorization.
It might be nice to interpret Common Core in an alternative way; the one that allows standard algorithms to be taught prior to 4th grade. The one that allows students to gain proficiency in the (shudder) procedure before being shown alternative methods that then serve to spotlight the underlying concepts. The way it used to be done when Brownell, (reformer of his day in the 40’s through 60’s and receives steady praise from today’s reformers including Alfie Kohn) wrote the textbooks that I used. Distinguishing main dish from side dish would be such a welcome change.
It might also be nice to not require “explanations” from K-6 students
Maybe they wouldn’t need to have parents make up the slack–or have students enrolled in learning centers.
