"The project title – „Maths around us” (MAU). Maths – “the Queen of science” was the most important subject of activities and cooperation between five schools. The project lasted three years. In each school there was a group of 50 students between 13-15 who worked at the project. They were supported by the majority of school and local society.The main aim of„Maths around us” project was to develop a wide range of maths, social, language and ICT skills through involving students in creative activities, noticing maths and its aspects in the surrounding world. All activities and communication was conducted in English. Our students understood that using foreign language fluently opens them the door to the world. Cooperation of teachers gave them the unique possibility of exchanging opinions, experience and work method observation. Our aim was also encouraging local society to help and to apply for Erasmus+ grands by other school from the region.Five schools from: Poland,Turkey, Italy, Spain and Bulgary were involved in the project.Gimnazjum Publiczne im. Mikołaja Kopernika in Ziębice in the last project year was transformed into Szkoła Podstawowa nr 2 in Ziębice im. Henryka Sienkiewicza – school coordinator (300 students, 40 teachers).

Students have achieved successes in sports and maths. School cooperated with Ecomission 21 – Bulgarian NGO and with EDC volunteers for two years. Students and teachers were involved into etwinning projects. Erasmus+ was their first project.Project was divided into five stages: : ""Maths in kitchen"", ""Maths in vehicles"", ""Maths in buildings"", ""Maths in nature"" and ""Maths in games"". Each school was responsible for one project stage creating the activities plan, organising work, taking care of the schedule and working at the final evaluation. During each stage students were involved in different maths matters and working results were presented online by means of different ICT tools. All activities were prepared in English. Each participant had the access to all materials on the Internet. Students worked in groups or pairs very rarely individual. One of the repeated activity was online communication when students found out information from each other and solved maths tasks. Students were also involved in local events promoting their project like celebrations, kermises, competitions when they presented their work to local society.Working at the project „refreshed” schools. Students achieved knowledge which is not included in school curriculums. Solving maths tasks from different life fields they saw that maths is everywhere. Maths tasks were designed in order to enrich students' knowledge about history, geography, tradition or even cusine charecteristic for the project countries. They broke the language barriers and developed social skills. During the project we created five etwinning projects, project blog, collages, photo exhibitions, competitions, songs, many movies, presentations, interviews, project logo, documents: “Bank of good lessons”, “Online lessons”, film handbook “How to use Formative assessments during maths lessons”, calendar, comics, leaflets, bookmarks, photobooks. Students, teachers and local society are convinced that due to taking part in the project they gained unique life value all the more for three out of five countries Erasmus+ project was conducted for the first time."
