There are many extramural activities available for children of all ages in Groningen. Not all of them are advertised in English, although the classes may well be possible in English, so always enquire about this!
Art, music and theatre
The main centre for art, music and theatre classes in the city of Groningen is VRIJDAG (site in Dutch only). They offer a range of walk-in classes, workshops, and long-running courses at three different locations in the inner city - also for adults! Their programme is renewed every six months and usually they have an open ‘lab week’ in January and again in September to help new participants to get to know their offering. Although the website is in Dutch, all classes can be offered bilingually so please enquire about the possibilities by calling or dropping by.
Music lessons are commonly offered by individual teachers who may even be able to come to your home for lessons. You can enquire at the local music conservatory, Prins Claus, or the student cultural centre, USVA, for student teachers. Local Facebook groups such as Groningen Mamas or Expats in Groningen are also excellent places to ask fellow parents for tips.
Science workshops and courses for older children (6 years +) are offered through De Jonge Onderzoekers (the Young Researchers), a non-profit organisation for extracurricular science education and training.
English language community based or informal activities for kids can be found and organised through groups such as Groningen Mamas Facebook group. Connect International organises community events for the expat community, both in the city and in surrounding areas. Ask at City Central for advice about new English language events for children in the city.
Public libraries organise activities for children and parents such as the Ouder-Kind café. Although these events are mostly in Dutch, the library is a good place to connect to parent communities.
