We illustrate a method, which is modeled on "breaching experiments," for studying tacit norms that govern classroom interaction around particular mathematical content. Specifically, this study ...

The inequality will be solved when \({m}\) is isolated on one side of the inequality. This can be done by using inverse operations on each stage of the sum. The final answer is ...

Storytelling and mathematics don’t naturally go together. The best way to spark a discussion about a math topic in a classroom can be unpopular with many students: solving word problems. Word problems ...

Masaki Kashiwara received the honor, often regarded as the Nobel Prize in mathematics, for work that combined different mathematical fields to solve challenging problems. By Kenneth Chang Masaki ...
