The fifth LTT events of our project was held virtually in June 2021, due to the epidemic organized by DITHESIO OLOIMERO NIPIAGOGIO AVLONARIOU, EVIA GREECE. The main purpose of the Greek LTT activities was to inform and support the kindergarten teachers to integrate Mathematics in preschool level. In this way, partners had the opportunity to: - virtually meet again before project closure; -Meet Greek preschoolers via ZOOM- presentations and icebreaker games; -Take a virtual school tour of the Greek institution (institutions, number of staff/students, etc.) -Understanding the Greek education system and preschool education system - get acquainted with greek culture (traditions, cuisine, cultural heritage) through a workshop and Kahoot game - meet the local community in digital sessions -Sharing good practices based on seminars - discuss about final report and distribution/finished products; -Sudoku in kindergartens, coding, robotic assisted coding, Math-oriented Montessorian Learning System, Handmade Math Games, chess These activities enriched teachers' knowledge and improved their skills and they decided to use the techniques and ideas they learned at this LTT meeting and introduced mathematics at the preschool level. Also: They learned how to relate Beebot to education, learned how to integrate mathematical activities into daily life, shared and learned good practices through workshops and brainstorm and learned about how the project process works. The teachers enriched their knowledge and developed their skills. Thanks to the SWOT analysis, the strengths and weaknesses of mathematics in the preschool curriculum were determined. In this way, participants developed their ability to analyze. In addition, sharing “effective and innovative teaching and assessment methods” by teachers increased the partners' experience on the subject.
