"Starting from the idea that one of the key competencies of the 21st century is the mathematical competence, the 5 European schools considered necessary to brush up the teaching methods and opened doors to educational innovation by taking Math outside the classroom. The fundamental idea to start up the present project was that about 73% of students from all the partner schools find Math boring and impossible to learn. In all partner schools were identified the needs to increase interest, curiosity and knowledge in mathematics, improve the mathematical skills of low achievers and create new materials in teaching math. Through ""MATHS GAMES"" project we raised students’ awareness and interest in learning Mathematics at our schools. Specific Objectives: -supported directly 68 students and 32 teachers to develop innovative cross-curricular materials during 4 international exchanges; -developed mathematical competence for the future to 80% boys and girls from 5 EU countries; -stimulated curiosity and creativity among students from 5 EU schools by connecting mathematics to real life; -increased interpersonal and intercultural communication competence among 80% participating students from 5 European schools; -improved mathematics assessment and learning using inquiry-based learning. ""Math Games"" project was addressed to students coming from 5 European countries and the direct target were students from lower secondary schools, in particular students who are 11- 14 years old. There happened 4 short term exchange of pupils (Italy,Romania, Lithuania and Bulgaria) and 1Transnationa Meeting in Turkey in the project. The total number of participants who attended the mobilities is of 68 students and 32 teachers . The project promoted an innovative approach that led to increase students’ interest and motivation in learning Math. The activities were designed to encourage learning by doing, by discovering, thinking skills, creativity, imagination, as well as, English and ICT skills. The implementation of the project was structured to achieve the project’s aims using the inquiry-based learning method. By tackling students’ curiosity in correlating math with the real world, they discovered by themselves the profound influence that math had on our daily lives. Four different topics were approached during the 4 exchanges of groups of pupils: MATH & ART, MATH IS FUN, MATH IN MOTION, and MATH IN SHAPES. Students’ mathematical skills, curiosity and creativity were developed using a cross-curricular approach. Students were encouraged to see the connection between Math and other school subjects like Art, Music, History, PE and ICT. Using games, team building activities, fundraising activities, surveys, Erasmus+ day events significantly contributed to enable students to learn through an international context. All the project’s products were created by students during the mobilities. During the hosting meetings the partners attended lessons, observed and exchanged good practices and got more familiarized with European educational systems. The school curricula expanded in accordance with the feedback and methods exchanged during the meetings. The following tangible results were achieved during the project: logo of the project, presentations, a brochure containing poems about Math, a common song, a calendar of the project, photos/ drawings, surveys about “Math in daily life - How Healthy Is Your Lifestyle?”, a travel manual, videos (“Using History to Teach Math”), Geometric toys, bookmarks, leaflets, questionnaires, a booklet of the project and the final DVD of the project. The intangible results were: increasing mathematics competence, improving mathematics assessment, stimulating creativity in teaching and learning math and developing motivation for using cross-curricular materials and inquiry-based learning in the educational process. The project presented a validated model of innovative and creative interventions for the development and improvement of teaching and learning Mathematics. This Erasmus+ project offered a wide range of opportunities for self-development for teachers to be updated with the last methods of teaching used in the European Union."
