My kids enjoy a couple of activities each week. My son is into sports, so he's been attending a nearby tennis academy twice a week. It's a great way for him to stay active and learn discipline. He also gets to socialize with kids his age and make new friends, which is something I'm glad about because he was quite shy before.
My daughter loves dance; she attends a ballet class on Mondays after school. I hope it helps her develop grace and flexibility, physically and mentally. She's also very vocal about her love for the stage, so I think it'll help boost her confidence too.
As for my hopes, I believe these extracurricular activities help complement their school education. It's a great way to keep them engaged and entertained, while also hopefully discovering their interests and passions. Creativity, confidence, and discipline are some key benefits that come to mind.
Art is a wonderful way to develop imagination; it's great that you're fostering your son's interest! Museum visits are an excellent educational experience and a chance for parents and children to bond too.
