8th grade · Expressions & Equations
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 10^8 and the population of the world as 7 times 10^9, and determine that the world population is more than 20 times larger*.
2 interactive, auto-graded activities for 8th grade students practising 8.EE.A.3. Mini Labs put the standard to work in a real scenario; Skill Practice builds fluency on the standard alone. Every one is randomized per student, so each learner gets their own numbers.
Blast off on a math mission through the solar system! In this interactive worksheet, students use scientific notation to calculate and compare planetary distances, travel times, and orbits. A fun, story-driven way to understand why scientists use exponential form to work with extremely large and small numbers.
Explore real-world measurements from the cosmos to the microscopic world while learning how to write large and small numbers in scientific notation. Students convert quantities into exponential form to make data easier to read, compare, and compute—building confidence with powers of ten and place value understanding.
