Teaching tips & learning objectives
Learning objectives
Explain how positive and negative powers of ten change the size of a number.
Connect single-digit scientific notation examples with their ordinary-number equivalents.
Teaching tips
Before revealing a conversion, ask whether the ordinary number should be greater than one or between zero and one. Use that estimate to check the direction of the decimal movement.
Follow the presentation with your own decimal-coefficient example to show why adding zeros is not a general conversion rule.
Good to know
Questions teachers ask about this resource
Does it cover decimal coefficients such as 9.54 × 10¹²?
No. The presentation explicitly leaves those conversions outside its scope and uses examples with a single nonzero digit.

- 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 × 108 and the population of the world as 7 × 109, and determine that the world population is more than 20 times larger.
