Our public schools, like others, have a Bring Your Own Device (BYOD) policy, starting in 5th grade, with Chromebooks being recommended. How can this help gifted students?

One of our children is given permission by his math teacher to do problems on Alcumus (a site of AOPS) when he knows the topic to be covered in class. This kind of informal accommodation is better than nothing, but if a child's work done more formally, for example through an AOPS course, this may help him or her get appropriate instruction in future years. In the high school, math classes beyond calculus are offered online.

What are your schools doing? What should be done?
