Lobster Diver is an educational math game designed for middle school and upper elementary students, specifically targeting grades 3 to 8. Players are immersed in an underwater adventure off the coast of Maine, diving for lobster traps and aiming to catch the elusive blue lobster while avoiding obstacles like the electric eel. The game is aligned with number and operations standards set by the National Council of Teachers of Mathematics (NCTM), focusing on understanding numbers, fractions, and their placement on number lines.

Developed as part of the "Math Snacks" initiative and in collaboration with Maine Cooperative Extension, Lobster Diver is one of the many educational resources available on the Math Snacks website. Created by a team of mathematics educators, researchers, and game developers at the Learning Games Lab at New Mexico State University, this game has undergone rigorous instructional design processes and user testing to ensure educational effectiveness.
