# Q1 W6 Sept 16-20 Pre-Algebra

Teacher Stephanie Durrance 8th Grade Math (Pre-Algebra) 8th 6 Focus 2: Properties of Exponents
Standard(s) Taught
 MAFS.8.EE.1.2: Use square root and cube root symbols to represent solutions to equations of the form x^2 = p and x^3 = p, where p is a positive rational number. Evaluate square roots of small perfect squares and cube roots of small perfect cubes. Know that √2 is irrational.

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

Learning Targets and Learning Criteria
 • recognize perfect squares and non-perfect squares and numbers that are perfect cubes. • recognize taking a square root of a number as the inverse of squaring that number and taking a cube root of a number as the inverse of cubing that number.  • evaluate the square root of a perfect square and the cube root of a perfect cube  • justify that the square root of a non-perfect square will be irrational and that the cube root of a non-perfect cube will be irrational.  • determine positive solutions for equations of the form x^2=p and x^3=p   • recognize a square root is the length of the side of a square and a cube root is the length of the side of a cube. • 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.
