PerciGo is a free maths fluency practice tool designed by a Perth-based educator for Australian classrooms. Aligned with Australian Curriculum Version 9.0, it supports students from Foundation to Year 8 across Number and Algebra, Measurement and Space, and Statistics and Probability. The platform helps learners build confidence and automatic recall through short, focused practice, with activities ranging from untimed sessions with hints to 60-second tests and extension challenges in logic, spatial reasoning, and multi-step problems.

Teachers can customise review tasks by year level and skill, host live competitive games, or use Choral Drill Mode for whole-class practice. Interactive tools include virtual rulers, angle drawing, and coordinate grids. Students receive immediate feedback and hints, and can earn achievement levels from Sprout to Diamond. For progress monitoring, teachers can connect a class to a private Google Sheet to track speed, accuracy, and achievements. PerciGo requires no student accounts or passwords and does not collect student names or personal information.
