The goal of mathematics curriculum for primary and secondary schools in European Union is to help students apply their mathematical knowledge and skills to solve problems and make decisions. However, there is a large number of students that faces learning difficulties with mathematics. 6% of students lack of mathematical skills, and specifically lack of arithmetic ability which seems to rely on different cognitive processes. Technology might play an important role in overcoming the above difficulties. Actually we assume that technology and more specifically 3D printing technology could aim students understanding and adoring maths. 3D printing is an innovative technology. An emerging problem is the cost of the filament. In order to solve the above cost problem, recycle seems to be an answer. The procedure of use waste in order to transform it to a filament, could reduce environmental pollution and might contribute to decrease the 3D printing cost. According to European Strategy on Plastic Waste in the Environment signifies that “the inherent characteristics of plastic create specific challenges for waste management”. The aim of 3D-ReMath is to help students understand better maths and become familiar with technology and the procedure of recycling. More specifically students could collect plastic (plastics caps, or bags, or pens, etc.) and then by using a proposed framework for transforming plastic to filament, suitable for 3D printers, they can use this material to print 3D objects which help them to overpass difficulties that they face in mathematics. 3D-ReMath aims pupils to understand maths, to reduce-reuse-recycle products and finally get them familiarized with an innovative fabrication technology. Activities of this project include: • A map that identifying maths disabilities and group them to categories based the grade of each disability. • Nine (9) curricula for teaching maths to students with disabilities, for recycling procedure, for 3D printing. • A framework for converting plastics to filament suitable for a 3D printer. • Three (3) face to face trainee programs for teachers. • A portal will be developed in order to upload materials of the project a communication spot between all partners and all stakeholders. • An overall report, with evaluation results and proposals about learning education methods and tools. • One (1) international conference entitled “Overcoming learning disabilities using technology and ecology”. 3D-ReMath will encourage students to use maths in their rural lives, skip any possible “fear” concerning maths and understand much better the theory of maths. 3D-ReMath Project will increase their imagination and empower their skills of problem solving and creativity as long as increase their ability of thinking-designing and producing. Teachers will be encouraged to introduce a “new world” to their students, a world that include non-fearful maths, positive actions of re-using plastic and non-usable items and the feeling that they can produce a new item by themselves. Participant Universities will gain from the 3D-ReMath Project due to teachers’ training sessions and the participatory design. Universities will develop their collaborative and communication skills and they will actively interact with the members of the 3D-ReMath Project (students, teachers, researchers, etc.).
