Buzzmath

Buzzmath is a website that takes a core aligned, middle school math curriculum and pairs it with flexible student progress monitoring features. Motivational narratives challenge kids to save Buzz City from math ignorance or track down the concept of zero in a historical context.

Kids can choose any lesson, respond to teacher messages and assignments, retry questions to earn stars on sets of 10 interactive questions, or elect to move on to enhancement and bonus sets.
