Parenting is by far the best profession/hobby. There is nothing more fascinating that observing and facilitating the development of a human being. Sometimes, however, it can be frustrating. Right now my daughter is 4. She's pretty smart (I know, all parents think so :-) ) and has an easy time learning things. Once concept that seems to be difficult for her is learning the concept of measurements. She will say something like, "Wow! That dog was 100 big!", and when I ask her "100 what?" she gets frustrated. Like I should realize that 100 is a really big number, so that means it's a really big dog. Given that she's only 4, I have no problem with that logic, but I would love to teach her about units and measurement.
So, here's where I need feedback. Does anyone know of a good site/method/book/movie/show to teach the concept of measurement to young kids?
