Arkansas Curriculum Frameworks
AR.Math.Content.8.EE. Expressions and Equations
AR.Math.Content.8.EE.A. Work with radicals and integer exponents.
AR.Math.Content.8.EE.A.1. Know and apply the properties of integer exponents to generate equivalent numerical expressions using product, quotient, power to a power, or expanded form.
AR.Math.Content.8.EE.A.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. For example: Estimate the population of the United States as 3 times 108 and the population of the world as 7 times 109, and determine that the world population is more than 20 times larger.
AR.Math.Content.8.EE.A.4. Perform operations with numbers expressed in scientific notation, including problems where both standard form 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.
