Thinking back most things she would ask me once, like she asked me what the name of a shape was and I had to look it up. I told her it was a quaterfoil, and she has known it ever since. I also once told her a shape was an elipse, and she told me, "well then an oval is an ellipse" LOL.
Most things she just pics up from talking with me or us reading. She knows all the months of the years days of the weeks, is starting to be able to understand telling time with clocks, learned her letters, counts, counts by 10's, can count objects, knows all colors, shapes, concepts of on, under, behind, between, etc., beginning addition and many more things that my friends are trying to teach there children who are 3,4,and 5. DD just seems to know, but examining it, I find I really don't have to teach her....if it is mentioned she learns it and then later applies it. No wonder she gets board so quickly.
Example would be I guess last night she was watching the Discovery Channel and ancient crocidiles that ate dinosuars and she can now spout off amillion facts and explained to her dad that the crocidile has a 4 chamber heart...and that other reptiles don't and that the crocidile bit the dino on the "buttocks" LMAO. So it seems like she just knows because often I forget or don't realize where she heard something, but truely she just does not seem to need any repitition. Once and she has it.
