When I was a primary school kid we didn’t have gifted and talented classes. Kids who were ahead of the class could continue doing more and more advanced maths, move onto the next year’s work, though in 6th grade the problems only went up to advanced 6th grade. I don’t know what you would do if you were smart but unsatisfied with maths, I guess you’d be disruptive.
