Scientific notation intuition

The  exercise appears under the 8th Grade Math Mission. This exercise introduces the idea of scientific notation and tries to strengthen the ability to recognize how to change numbers into scientific notation.

Types of Problems
There is one type of problem in this exercise:


 * 1) Move the decimal to the appropriate spot: This problem has a manipulative that involves a number in which the decimal can be moved, and another figure will represent the number as a*10^n based on where the decimal is located. The student is expected to move the decimal spot to the right place to have the number be in scientific notation.Sni1.png

Strategies
As long as one knows what scientific notation looks like, this exercise will be correct every time.
 * 1) Strictly speaking, a number is in scientific notation if it is written in the form of a*10^n where n is an integer and a is a number such that $$ 1 \leq a <10 $$.
 * 2) It is not necessary to submit the problem until it is correct.
 * 3) Slide the decimal to ensure it is immediately after the first non-zero number read from the left. Submit.

Real-life applications

 * 1) As it can be inferred, scientific notation has many applications in the sciences.
 * 2) Scientific notation is useful for representing very large or very small quantities.
