Here’s a puzzler: Why are the Common Core math standards accused of fostering “fuzzy math” when their drafters and admirers insist that they emphasize basic math, reward precision, and demand fluency? Why are CC-aligned curricula causing confusion and frustration among parents, teachers, and students? Is this another instance of “maximum feasible misunderstanding,” as textbook publishers and educators misinterpret the standards in ways that undermine their intent (but perhaps match the interpreters’ predilections)? Or are the Common Core standards themselves to blame?
My take is that the standards are in line with effective programs, such as Singapore Math, but textbook publishers and other curriculum providers are creating confusion with overly complex explanations, ill-written problems, and lessons that confuse pedagogy with content.
Many of the “fuzzy math” complaints seem to focus on materials that ask students to engage in multiple approaches when tackling arithmetic problems. But to understand whether the confusion stems from the standards or the curriculum, let’s start by recalling what the CCSS actually require.
1. The Common Core explicitly demand student mastery of the standard algorithms for addition, subtraction, multiplication, and division for both whole numbers and decimals.
Any honest reading of the standards must recognize that in grades 4, 5, and 6, the Common Core demand that students master standard algorithms. In grade 4, students should “fluently add and subtract multidigit whole numbers using the standard algorithm.” By grade 5, they are expected to multiply whole numbers using the standard algorithm. And by grade 6, they are expected...
