With a colleague from Greece, I started a project for 6-12-year-olds where they would explore their family relationships, using photographs, interviewing older family members, and things like that. Since February, the teachers from Bosnia and Herzegovina, Bulgaria, Croatia, Greece, Lithuania, North Macedonia, Poland, Romania, Serbia, Spain, Turkey, UK and Ukraine have joined the project, and shared the activities done with their students.
Even my older students enjoyed the Kahoot quiz about family members.
