For this scientific numbers worksheet, learners change numbers from standard notation to scientific notation.  This two-page worksheet contains 19 problems.  Answers are provided on the last page.

Use a resource on which you can base your lesson on base 10 and scientific notation. The second installment of a 35-part module presents scholars with a review of scientific notation. After getting comfortable with scientific notation,...

Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

Sal uses a TI-85 graphing calculator to demonstrate how to check his work while he solves a complex word problem where he must use scientific notation to express his answer. This would be a very useful video for an SAT prep or cumulative...

Scientific notation is defined and used to express the number 0.0000000003457. This concept is not as clearly defined as it could be, and is probably not suitable for those who have not had prior experience with the concept.

The problems in this video contain additional examples of scientific notation, continued from the previous presentation. Viewers have the opportunity to see Sal work through several more problems using the same techniques he has been...

Apply the concept of scientific notation to a word problem involving the rate of speed. Sal explains how to express the answer in scientific notation.

Explore the conversion of numbers to scientific notation and back again. Learners begin with a matching activity to identify equivalent expressions. Then guiding questions test and extend their understanding.

Why does the equal sign look that way? The resource explains the reason several of the math symbols look the way they do. Using a few specific examples, the video points out that some symbols are rooted in their meanings and others are...
