Two mathematics questions for third graders in the US has created an online furore after it showed that a student was marked negatively even though his answer was correct.

In the first question, which was posted on Reddit, students were asked to “use repeated addition strategy to solve: 5x3”. The student wrote “5x3=15” and substantiated the answer by writing “5+5+5” to show how he solved it.

The third-grader was evaluated negatively because according to the ‘key’ the way to arrive at the answer was “3+3+3+3+3”.

The second question asked the students to “draw an array to show and solve: 4x6”

The student drew six rows and four columns of dashes and wrote that the answer is 24. But he was again negatively marked because the key said four rows and six columns of dashes.

The two answers have gone viral on various social media platforms with people commenting both for and against the evaluation criteria. There were 10,766 comments on the Reddit post when this article was published.
