Starting in Kindergarten, Computer Science is taught to every student at PS 84 in the Technology classroom.

Kindergarten students are introduced to the world of code/programming with the curriculum. They creating computer programs with loops and events, and algorithms for everyday tasks using Blockly Language.

Through this they learn to collaborate with others meaningfully, investigate different problem-solving techniques, persist in the face of difficult tasks, and learn about Internet safety. By the end of this course, students create their very own custom game or story that they can share.

Students in 1-4 grades are taught using Tynker, a game-based curriculum where students move at their own pace through scaffolded lessons to learn concepts and apply them creatively. 

Tynker is designed to integrate coding into core academic subjects and is built around project-based coding lesson. Course work is determined by experience and grade level. Tinker is part of the DOE’s STEM Computer Science Initiative.

By grade 5, students learn Intro to Python level 1, which uses fun and engaging single-lesson projects to teach students the core concepts of coding. Topics include: Variables, Data Types, Lists, Loops, If-Statements, and Functions. Students also learn how to debug their programs.

Meet the Teacher


Mr. Frezza

John Frezza grew up on Long Island, and spent 15 years working in marketing before he decided to become a teacher.

He joined PS 84 in 2008 as the Technology/Computer Science Teacher, and instructs students K-5.

He came to teaching because he loves the idea of helping children not only academically but also in life, and loves teaching computer science because it ties into his philosophy: that children should challenge themselves to be the best they can be.

Mr. Frezza encourages his students to believe in themselves and know they can accomplish anything when they put their minds to it, no matter what anyone tells them, no matter what the obstacle.

He believes coding empowers students to think outside the box and to be problem solvers. That, with perseverance, comes success.
