 7th Grade Number Sense:  Standards and Practice Problem(s)
Mathcasts/
ExamView
7NS.1.0 Students know the properties of, and compute with, rational numbers expressed in a variety of forms:  


7NS.1.1 Read, write, and compare rational numbers in scientific notation (positive and negative powers of 10) with approximate numbers using scientific notation.

 

 

 

Note: If you watch Bruce's VoiceThread you'll notice that the ink keeps disappearing.  To prevent this you have to click on the center circle in the color wheel one or more times.
