# Q1, W6: October 5-9 Pre-Algebra

Teacher Kristin Andreason Pre-Algebra 8 October 5-9 Focus 2: Properties of Exponents and Focus 3: Scientific Notation
Standard(s) Taught

MAFS.8.EE.1.1: Know and apply the properties of integer exponents to generate equivalent numerical expressions.

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
• determine the properties of integer exponents by exploring patterns and applying my understanding of properties of whole number exponents.
• explain what it means for a number to be raised to a power and how to represent the repeated multiplication symbolically.
• explain when parentheses are required for bases when generating equivalent expressions.
• apply the properties of integer exponents to simplify expressions.
• 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 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
