As a substitute teacher and mom of two gifted children in a public elementary school, I would advise you to ask for a meeting with the school regarding the gifted or enrichment program for children. You have to be their advocate and ask for challenging materials. When a child is sneaking to read a book under their desk, they're bored! BTW, the gifted kids are always reading books under their desk when the teacher is going over homework, busy work, or reviewing old material. It doesn't bother me unless it's new material that I'm introducing!
