Common Core Writers: Controversial Math Problem Not Common Core-Aligned

The Hechinger Report (3/27) reports on the recent “viral” response to a Common Core-inspired math question posted by a frustrated father, noting that “critics say the problem takes a simple one-step subtraction problem and turns it into a complex endeavor with a series of unnecessary steps, including counting by 10s and 100s.” The article notes that Jason Zimba and William McCallum, lead Common Core writers, said that “a poorly written curriculum” is to blame, quoting McCallum saying, “It’s a complete reversal of the truth to call this a Common Core problem.”
