# Q1 W9 Oct 7-11 Pre-Algebra Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 9 Focus 3: 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.

Learning Targets and Learning Criteria
 • write very large and very small numbers in scientific notation.  • compare numbers written in scientific notation to determine how many times larger or smaller one number written in scientific notation is than another. • 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 10a”.
