• Digital, interactive content can support active learning and provide both motivation and an automated feedback to students. Unfortunately authoring interactive content remains a difficult task for teachers. There are few interoperable standards and e-learning platforms often restrict what is technically possible. Even if some teachers create amazing interactive content it is challenging to publish and share this content with colleagues. This paper proposes a way to leverage Web Components, a rather new technology supported by modern browsers, to allow teachers to quickly author interactive exercises involving mathematical expressions and visualizations. As Web Components are standardized they can be shared and embedded in any website. The proposed Web Components for mathematics allow for: 1. A convenient visual input method for expressions and formulas, 2. A sophisticated validation system for these expressions in order to give immediate feedback to students on their solutions.
