Grade Level/ Course: 8th Grade Standard with code: Domain: 8.EE.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 × 108 and the population of the world as 7 × 109, and determine that the world population is more than 20 times larger. Expressions and Equations Cluster: Work with radicals and integer exponents. Type: ______Knowledge ___ X ___Reasoning Knowledge Targets Express numbers as a single digit times an integer power of 10. ______Performance Skill Reasoning Targets Compare quantities to express how much larger one is compared to the other. ______Product Performance Skills Targets Product Targets Use scientific notation to estimate very large and/or very small quantities.
