8.EE.A.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.

__Student Objectives__

Given a number in scientific notation, I can write it in standard form.

I can add and subtract numbers given to me in scientific notation.

__Bellwork__

Students will turn in homework.

Students will complete rating ticket for Friday's scientific notation scramble.

Students will complete the scientific notation conversions quiz.

__Common Core Standards__

8.NS.A.1 Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number.

8.NS.A.2 Use rational approximations of irrational numbers to compare the size of irrational numbers, locate them approximately on a number line diagram, and estimate the value of expressions (e.g., π2).

*For example, by truncating the decimal expansion of √2, show that √2 is between 1 and 2, then between 1.4 and 1.5, and explain how to continue on to get better approximations*.

__Student Objectives__

I can identify natural numbers, whole numbers, integers, rational, irrational, and real numbers.
