THE REASON FOR THE PROJECTMulticulturalism is one of the most significant changes in many school systems, especially when primary and lower secondary education is concerned. So far, European countries have paid little attention to maths education in multicultural contexts. Differences in cultures and languages make the maths teaching-learning process harder than it is.EXPECTED OUTPUTS1. DVD with proposals for teaching materials designed for communicating and teaching maths in multicultural classrooms, to be used in schools, and teacher trainers and trainees. [in EN and partners languages]The materials, with video-clips, include:• analysis and comparison of case studies in the partner countries• teaching materials prepared and co-piloted within the partnership and in the associated schools2. Website with materials in the DVD [in EN and partners languages, without video-clips]3. Book with same materials as in the DVD [in EN, without video-clips]4. Courses and workshops for teachers and trainees to pilot the teaching materials.5. International Conference to present the project results, with workshops.ENVISAGED IMPACT Increased attention to communication in maths classes, careful and precise use of the language, and better acknowledgment and valuation of the cultural differences in multicultural classrooms, represent the methodological change which minority pupils and the whole class could benefit from.
