Are you a teacher looking for free, high-quality interactive maths activities?
Are you tired of paying licence fees, subscriptions, or hidden costs? Frustrated by slow, complicated, or restrictive applications? Imagine a web platform with hundreds of small, super-fast-loading mathematics activities, with no ads, no subscription fees, and no hidden costs.
What is Apoplous?
Apoplous is an open educational initiative created by a team of teachers in Cyprus. We are building a bilingual primary mathematics library through small HTML5 learning units that are practical, clear, and ready to use in classrooms, support teaching, revision, and home learning.
Why support is needed now
Apoplous has already begun with sample Grade 4 content. The pilot shows the value of the idea. We now need support to turn this first step into a stronger, richer, and more structured open educational resource.
What this campaign will fund
This campaign will help us:

What makes Apoplous special
Apoplous is not being built as a closed commercial product. It is being built as a shared educational good that will remain:
Our vision
With support now, Apoplous can grow into a meaningful open mathematics library for primary education, with lasting value for schools, learners, teachers, and families.
Apoplous is a bilingual educational initiative created by a team of teachers in Cyprus. It aims to build an open, ad-free mathematics library for primary education, based on small HTML5 learning units that make mathematics easier to teach, easier to learn, and easier to share.
What makes Apoplous different
Main goals of the campaign
Why this campaign matters
This campaign will help Apoplous grow from an initial pilot into a stronger open mathematics library for primary education, created by teachers for children, teachers, families, and schools.
Why this is important
Access to good educational material should not depend on cost, language, or commercial platforms. Teachers and families need mathematics resources that are:
This need is what led us to create Apoplous.
Apoplous is an open bilingual mathematics library based on small HTML5 learning units that can be used:
The project is aimed mainly at:
Its importance also comes from the fact that it is a teacher-led initiative with a strong public purpose: to make mathematics more approachable, more reusable, and more widely accessible. By remaining open, translation-friendly, and free from advertising, Apoplous aims to create lasting educational value for a wide community.
Why it can grow beyond its immediate audience
Apoplous is also important because it already connects naturally with existing educational networks and communities that can become early supporters, users, and multipliers of the project.
Because of these links, Apoplous is not starting in isolation. It is being developed within a wider ecosystem of teachers, educational communities, STEM networks, and public-facing learning spaces. This gives the project a stronger chance to create real impact, reach early users quickly, and grow into a meaningful open educational resource with value both in Cyprus and beyond.

Previous Experience & Collaborations
Apoplous is also important because it does not begin in isolation. It grows out of existing educational outreach, collaborations, and recognised networks that can help the project reach users quickly and create impact from an early stage.
Because of these links, Apoplous has the potential to benefit not only teachers, students, and families, but also a wider circle of:
This gives the project a stronger foundation for early adoption, wider dissemination, and meaningful long-term educational value.
Our social commitment is educational. Apoplous is an open educational initiative created by a team of teachers in Cyprus, aiming to make primary school mathematics more accessible through small, clear, bilingual HTML5 learning units. We want to support children, teachers, and families with practical materials that are easy to use, revisit, and share. The project is designed as a public educational resource: it will remain open, free from advertising, open to translation into any language, and, where possible, open source. This commitment reflects Goteo’s focus on civic, educational, and commons-based projects, and places learning, access, and collaboration at the centre of our work.
