MCC8.EE.3 Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other. For example, estimate the population of the United Sates as 3 x and the population of the world as 7 x , and determine that the world population is more than 20 times larger.

MCC8.EE.4 Perform operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used. Use scientific notation and choose units of appropriate size for measurements of very large or very small quantities (e.g., use millimeters per year for seafloor spreading). Interpret scientific notation that has been generated by technology.

EQ: How can I represent very small and large numbers using integer exponents and scientific notation?

How can I perform operations with numbers expressed in scientific notation?

How can I interpret scientific notation that has been generated by technology?

Scientific Notation

What is the value of 10 * 10 * 10 * 10 * 10?

Is there a more efficient way to write this with fewer digits?

What is the value of 7.2 * 10 * 10 * 10 * 10 * 10?

Can you write this as a multiplication problem with fewer digits?

An ordinary quarter contains about 97,700,000,000,000,000,000,000 atoms.

The average size of an atom is about 0.00000003 centimeter across.

Example 1

The length of these numbers in standard notation makes them awkward to work with.

Notes: If I were you, I'd write these down. ( I'm just sayin'.)
