Under Links on my webpage, I have two new ones, one in the Math section, and one in the Language Arts section.
Under Math, click on it and then you will see the list. Go to "Decimals and Scientific Notation" The first part is good, but at the 3:30 mark, that's when they discuss scientific notation. The lead up to it is good.
Under Language arts, click on it and then you will see the list. Go to "Possessive Nouns". It is a nice presentation of one of the most mixed up things (by students AND adults) that there is in punctuation.
