All the main points you need to teach kids how to covert numbers from scientific notation to standard notation and back again. This covers both positive and negative exponents. It is in the form of a foldable that can be put into a math or science interactive journal. It breaks down all parts of converting numbers into easy to manage steps and can be used to teach/re-teach students about converting with scientific notation. I usually start with the front of the foldable, but I hold off on the rule part at first, then I move to the "Positive Exponents: Scientific Notation to Standard." After they get a good handle on that portion, I go back to the front and talk about the rule of the first number, then have them practice identifying when the number is correct. Next, we go to "Positive Exponents: Standard to Scientific Notation. I follow that up with the Negative Exponents section. This is a great resource that students can easily reference back to when they forget how to convert later on in the year. This is extremely useful for teaching TEK 8.2C of the 8th grade math standards, convert between standard decimal notation and scientific notation. I had one person report that it was messed up when they downloaded it. It is fine on my end, but you may want to try moving the margins at the top and left of the paper out because I did that at the beginning and it may be what is messing the document up.
