Abstract
The national STEAM project “My House”, second edition, carried out during the 2024–2025 period, aimed to develop the interdisciplinary competences of 10th–12th grade students through the integrated application of mathematics, informatics, and technological education. The project activities included the creation of a 2D digital design of an individual house using Microsoft Visio, budget estimation for interior and exterior renovation works, research of the construction materials market and the banking sector, as well as performing specific mathematical calculations. The practical component was complemented by building a model from recyclable materials and presenting the renovation stages, highlighting the effectiveness of the STEAM approach in developing applied competences.
