Thanks for this article. As a father of four, and vehement enemy of all things mathematical (I teach art), seeing this kind of thing coming from my child’s school would have infuriated me. You’ve provided a great explanation for why the teacher marked it incorrect and also why it’s important for a student to understand that. Nicely done. And while you haven’t converted me to a math person, this is a good reminder to me, to trust those people who are experts in their fields to do what they have studied and trained to do.

One clap, two clap, three clap, forty?

By clapping more or less, you can signal to us which stories really stand out.
