Teacher Felicia Taylor Intensive Math 8th Grade 19 Focus 7: Scientific Notation
Standard(s) Taught

MAFS.8.EE.1.3

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.

MAFS.8.EE.1.4

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.

Learning Targets and Learning Criteria

Students are successful when they can:

• re-write very large and very small numbers in standard form to scientific notation.
• compare quantities written in scientific notation to determine how many times bigger one number is than another using scientific notation.
• add, subtract, multiply, and divide numbers written in scientific notation by applying laws of exponents.
• select the appropriate units for very large and small quantities when solving problems.
• demonstrate on the calculator and identify that E on the calculator means x 10^a.
