The Common Core math quiz that has everyone outraged isn't about Common Core -- it's worse
A bafflingly graded third grade math quiz caused a firestorm on Reddit last week, and has spread across the Internet, causing several people to question Common Core math standards and the teacher's implementation of them.
The quiz is on some of the most fundamental aspects of basic whole number multiplication and how students encountering multiplication for the first time can think about problems.
The first question asks the student to calculate 5 x 3 using repeated addition. The student wrote 5 + 5 + 5 = 15, and was marked wrong, with the teacher writing in the "correct" solution of 3 + 3 + 3 + 3 + 3 = 15.
The second question prompts the student to calculate 4 x 6 using an array. The student drew an array with six rows and four columns, getting the answer that 4 x 6 =24. The teacher again marked the question wrong, and drew in a nearly identical array of four rows and six columns:
One possible rationale for the grading scheme could be a formalistic issue: The curriculum or teacher might have formally defined multiplying together two whole numbers A and B as the total number of objects in a collection of A groups of B objects each. In that case, 5 x 3 would be defined officially to be 5 groups of 3, or 3 + 3 + 3 + 3 + 3.
