This video indicates it is for prealgebra, 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 wha...t 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.

This is a good slideshow (61 slides) to use in a classroom. If the slideshow is expanded to 'full screen', the slides should be easily viewed with a projector as the font size is large.
The slides have test questions on place value, estimation, r...ounding, fractions, mental math, multiplication, numbers in standard form, etc. Pause the slide after each question to allow students to answer as the next slide has the answer. These slides would be suitable for fourth and fifth grades.
