Alessandra King

Alessandra King explores mathematics with her students at the Holton-Arms School in Bethesda, Maryland. An astrophysicist by training, she has taught physics and mathematics at the middle and high school levels on three continents—in Milano (Italy), Manila (Philippines), and the greater Washington area (USA). Alessandra is a member of the editorial panel for the NCTM journal Mathematics Teaching in the Middle School (MTMS) and has published articles and blogs in various professional journals, such as MTMS, AMLE Magazine, JAIMS, The Australian Mathematics Teacher, and Mathematics in School. She greatly enjoyed collaborating with TED Ed on a couple of TED Ed lessons on the history of numerical systems and on banned numbers.
