## What is Oyster | Middle School Math?

OYSTER TURNS MATH FROM A LIST OF ASSIGNMENTS INTO A JOURNEY WORTH EXPLORING.

Designed for Grades 5–8, Oyster helps students discover what’s coming next in math before they meet it in class. With a clear learning path, 4,000+ teacher-created interactive activities, and a game-like galaxy to explore, students always know what to learn, practice, and improve next.

FLIPPED LEARNING: Learn before class. Practice with purpose. See yourself improve.

WITH OYSTER, STUDENTS CAN:

* Explore upcoming math topics before class and walk in prepared

* Build skills across numbers, fractions, algebra, geometry, measurement, data, and probability

* Learn by doing with number lines, matching, drawing, model building, object hunts, visual problem solving, and more

* Turn daily practice into a habit with missions, streaks, rewards, and badges

* Revisit challenging concepts and strengthen skills that need more practice

* See progress across different math abilities with the Skill Crystal

* Explore six unique worlds, unlock new avatars, and choose their own captain

* Learn in an ad-free environment designed to keep the focus on math
