The method is based on group cooperative learning and teaching the acquisition of each team member to each other (intertwining individual and team learning). The mosaic is a method that builds confidence in the participants’ own strengths; develops communication skills (listening and speaking); reflection; creative thinking; problem solving; and cooperation. Steps in engaging the activity The teacher asks for the formation of teams of four students. Each team member receives a number from one to four. Students are grouped according to the received numbers. They are cautioned not to forget the composition of the original groups. Newly formed teams receive personalised cards that contain parts of larger material (the material has as many parts as the groups are formed). The teacher explains the topic to be addressed. Expert groups analyse the material received, consult each other and decide how to present the information to the members of the original groups.   https://link.springer.com/chapter/10.1007/978-3-030-34258-6_10">https://link.springer.com/chapter/10.1007/978-3-030-34258-6_10
