So true, HK. Your suggestions are really helping me as you have btdt. While I have no idea how gifted my child is, she doesn't seem to need repetition and can understand abstract concepts without concrete representation. However, she also enjoys manipulatives. She wants to touch, smell, observe, use her body all the time. So I am trying to create an environment which gives her a rich sensory experience. Based on your recommendation, I started doing more research on CM. I checked out a book by Catherine Levison from the library. Thanks again for your ideas.
