Scientific Notation II: The Mantissa

In this scientific numbers worksheet, students 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...

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 handy video for an SAT prep or cumulative review.

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.

Explaining scientific notation is useful because "it allows us to write large or small numbers in ways that are easy for our brains to write down and understand." Sal proceeds to solve a few practice problems involving scientific...

This video contains additional scientific notation examples, continuing from the previous presentation. Viewers can see Sal work through several more problems using the techniques he has outlined throughout the pre-algebra video series.

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

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. 

Numbers with lots of zeros, lots and lots of zeros. Decimal points to the left and decimal points to the right. Now multiply these numbers. Daunting. There's a shorter way to do it, use scientific notation. The teacher demonstrates just...
