Mr. Esposito

Hello Riverside families, 
Welcome to the 2020-2021 school year at Riverside High School. 

My name is Mr. Esposito, and I will be your math teacher for the 2020-2021 school year.  First, I would like to send my best wishes to you and your families during this challenging time. Second, I want to provide you with important information regarding this school year, more specifically, I would like to answer the following three questions for you:

  • How will students access their math class, lessons, and assignments this school year?
  • What’s the best method for students and parents to contact their teachers?
  • When is the first class and first mathematics assignment due?

Accessing your math class, lessons, and assignments

In order to access important class information, you will need to use and become familiar with Microsoft Teams. In order to log into your Microsoft Teams account, you must use your email address provided by the Yonkers public schools. If you are having any issues logging into your Yonkers Public Schools email, please reach out to Riverside’s Library Specialist, Mrs. Westphal, by email at

Contacting your math teacher

The best method for communicating with me this school year will be through my Yonkers Public Schools email: If you or your guardian would like to access information about your math course throughout the semester, please continue to visit this website, my teacher homepage.
