We are sending/have sent both of our children to a play-based preschool, where no academics are presented at all, and we love it. They focus on learning through play, and each child is able to process whatever is important to them. My kids explored/are exploring the academics that they're ready for, at home with us.
My kids are probably more in the "pleasantly" or "optimally" gifted range, so I'm speaking from that level. The play-based model helped us miss our eldest's giftedness until the summer before he started kindergarten (I don't have early readers, and had no idea that our adult conversations at age 3 were unusual), but it also meant he wasn't bored stiff listening to the teacher teach numbers when he could already add and subtract fractions. Their classmates have ranged from "regular" preschool aged kids to gifted early readers, or early math kids like my eldest, and it's accommodated all of them very well. Hopefully you'll love your preschool, but if you find yourself looking for a change, a play-based preschool might be worth investigating.
