Social networks are explored as educational tools, but results remain contradictory. The goal was to assess families' response to a Facebook group created to support class work and expand it to homes. Forty parents (27 mothers, 13 fathers) participated. A pre-experimental one-group post-test-only research design was followed. The group's activity was analysed using Gytrics, while interviews were conducted with parents. Quantitative results showed that the group had a significant impact: a high percentage joined the group, its reach was 100% (all participated), there were 15,875 visits, 502 publications (103 made by parents), 2823 reactions, Tuesdays and Thursdays were the most active days and 21:00-22:00 the most active hours. Qualitative results showed six themes: change in the perception of the subject, novel experience, interesting/positive, learning community, safe environment and reasons to join. The use of Facebook to support class work had a positive impact on parents, connecting school and family.
