What Decimators is
Decimators is a browser-based mathematics education platform for elementary learners aged approximately five to ten. Its games practise counting, addition, and subtraction through activities where players count black holes, choose eggs, and fire the exact number. The service includes adaptive learning, gamified practice, progress tracking, and scoreboards. Parent and educator portals provide account and learning management: parents can monitor children and manage multiple accounts, while educators can manage classrooms and track students through a dashboard. Child and student profiles are sub-profiles created by adults, so children do not provide email addresses or contact information directly. Full access requires a paid subscription or valid coupon code. Plans cover one player, parents with up to two or five children, and educators with up to 20, 50, or 100 students. Decimators was founded in 2025 and is based in Cape Town, South Africa. The listed platform is web.
