This video indicates it is for pre-algebra, but it is good for all levels, beginning, for those who need extra help, or those who need to review. This video is good and contains humor along with the lesson. Reviews what digits are, then goes into what the different place values are. This also contains what the place values are on the other side of the decimal. Then examples are gone through, they also go through the written number (long word form). Video is good quality and good for all students as review or initial learning of the concept.
