Free math activities
The interactive mathematics activities currently available on this website run in your web browser. They do not require an account, collect students' names, or send mathematics answers to HUBMATH EDUCATION. Your answers and choices are processed locally on the page.
Our current learning pages do not use advertising trackers, analytics scripts, or user sign-in services. We do not maintain personal student accounts or online progress records.
Images and technical information
The H+ logo and the author's photograph are hosted as website assets. Selected portfolio pages may also display public project or product images from sources such as HUB da Matemática, Google Play, or an original project image host. When your browser requests those images, the relevant host may receive ordinary technical connection information such as IP address, browser information, and access time. Our website host may receive the same type of ordinary connection information for pages and local assets.
Links to other educational websites
The site links to external educational and academic resources, such as the Virginia Department of Education and University of São Paulo, and selected Brazilian mathematics projects. These external websites operate under their own privacy practices.
A place for independent learning
Children and families can explore the public mathematics resources without sharing personal information. Any later changes that introduce personal information or student accounts will require a revised privacy notice and appropriate safeguards before they are made available.
