Worksheets? Yikes!
Being gifted doesn't mean a love of "schooly" stuff. It's an aptitude for learning-- which often is likelier exemplified by asking incessant questions, a reputation as the most legalistic four-year-old on the block (or the planet), or dismantling the TV/dresser/baby locks (possibly to see how they work, possibly to get parts for his planned World Domination Robot).
Gifted also doesn't necessarily mean being an early reader. Reading is a developmental task, and gifted kids are notorious for asynchronous development. One of my kids' friends (also ID'd gifted) didn't read until he was nine, though at twelve he reads as well, and as much, as my reading-at-five son. (There are studies that suggest math aptitude is developmentally linked as well.)
The schools, and sometimes us as parents, like to assume gifted kids are all of a kind, and all fit into a neat little box. Sometimes we just need to remember than anyone that bright can surely find his or her way out of the box (and probably turn it inside-out and sideways). <ggg>
