"PISA (Program for International Student Assessment) carried out by a consortium overseen by the OECD (Organisation for Economic Cooperation and Development) is the largest international test of students' skills in the world including mathematics as one of the basics of teaching level assessment where Poland is on the 18th position among the countries studied and needs innovation to improve this position. According to the report ""Teaching Mathematics in Primary School"" of the Educational Research Institute in Warsaw, although the syllabus is an important condition for high quality mathematics teaching, it is not sufficient and the substantive and methodical skills of teachers and the quality of teaching aids play an equally important role. This research also revealed the lack of comfortable mastering mathematics teaching methods among teachers and the adoption of concepts compatible in every detail with a textbook without a creative approach to the use of mathematics in the students’ daily life.In response to this situation, within the project ""MathemaTIKs for Primary School teachers"" we will develop innovative tools and methods to facilitate the teaching of mathematics in a motivational manner, allowing to balance the development of accounting and algorithmic skills with developing creative reasoning skills not only in our country, but also at the level of the entire European community.In order to achieve this, three members of our Strategic Partnership, Polish Primary School Klasyk in Puławy, Latvian Primary School Skibes and Spanish non-governmental organisation PASOS will conduct research and training in teaching methods and best practices promoting effective education in our countries and facilitating the achievement of intellectual outputs (book, short didactic films and e-learning platform).The study visits will take place in Poland, Latvia and Spain, and the intellectual outputs will document the results of our work and ensure the availability of developed methods and tools for all interested teachers. In order to properly implement the ""MathemaTIKs"" project, we have also planned 3 international project meetings: Kick off, an intermediate meeting and an evaluation meeting, and three multiplier events, one in each of the partner countries.We expect that the project will help to improve the quality of mathematics teachers' work in primary schools, and, therefore, the process of acquiring knowledge among the students. Teachers participating directly in the project will increase their ability to carry out research, introduce innovation, create teaching materials and improve their language skills which will also improve their ability to work in an international environment.Through an invitation to participate in the study visits issued to other educational institutions and local and regional organisms, the Strategic Partnership will strengthen its international network of contacts which will allow the project to have an increased impact and enrich it significantly. Our European activity will also improve and result in the promotion of further development and implementation of Erasmus + projects aimed at introducing innovative improvements in the teaching system."
