The model of training future primary school teachers for the formation of students’ skills to cooperate in a team is developed and experimentally tested in the article. There are the following components of this model: goals, methodological approaches, content (the structure of the ability to work in a team is considered), the main stages, forms, methods, means, diagnostic tools and the result of the studied training. The skills to cooperate in a team are explored in the article as a complex formation and as one of the soft skills. At higher education institutions, the future teachers training for the formation at primary school students’ skills to collaborate in a team takes place mainly during the implementation of interactive, game and project methods. However, this training needs to be improved. The developed experimental model implies systematic work on the basis of Pedagogy of the Heart and Pedagogy of Success, as a methodological basis of the researched process; equivalence of tendencies of using group work to improve learning outcomes and group work as a means of formation of students’ ability to interact. Experimental verification proved the effectiveness of the designed model: the number of representatives at a high level of readiness to develop primary schoolchildren’ ability to work in a team significantly increased and there were no low-level representatives.
