Scientific Notation

Solutions, examples, videos, and lessons to help Grade 8 students learn to how to 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.

Common Core: 8.EE.3

Suggested Learning Targets

  • I can express numbers as a single digit times an integer power of 10 (Scientific Notation).
  • I can use scientific notation to estimate very large and/or very small quantities.
  • I can compare quantities to express how much larger one is compared to the other.
The following figures show how to convert to scientific notation. Scroll down the page for examples and solutions.
