My son's teacher knew last week that my son has a high IQ and he is way above his kinder classmates. I even emailed her the skills that my son has so she can differentiate during centers time. I put him in the dual language class and right now the two teachers (spanish and english) agreed to put my son more in the spanish class. During centers, he is also doing more writing and spelling(his weakness). As of math, I don't see any differentiation yet. We'll see in the next few weeks. Just keep in touch with your child's teacher and show her that you are willing to support. Teachers sometimes are overwhelmed with lots of things most especially when they have such high students in the class.
