Meet the Filipino math genius and distinguished teacher of the year behind “Numberbender” videos

A Filipino teacher in Barstow, California is making unconventional waves in the field of mathematics.

Dr. Peter Esperanza developed these free online math videos for teachers and students.

“Numberbender” is Dr. Esperanza’s portal for his flipped classroom model, which contains video lectures in algebra, statistics, trigonometry, pre-calculus and calculus, both in English and in Filipino.

Using Esperanza’s Numberbender videos, many of his students have earned passing scores on the AP statistics exam, and he has seen an increase in the AP calculus pass rate.

In 2015, Esperanza was Apple’s distinguished educator awardee, and was awarded as Barstow Teacher of the Year.
