There's a difference to having the right to something and being forced to do something. For example all states give the right to a K-12 education, up to a point (usually there's age limits, and some states also have pre-k).

However just because children have the right to go to school doesn't mean they're forced to actually go and sit down (eg Wisconsin v Yoder). The courts do recognize that parents have the rights to force their kids to do certain things. Eg you can ground your child and it isn't "forced confinement", you can make them go to school and it isn't slavery, etc. Those exemptions pretty much go away once someone turns 18
