Math Planet: Algebra 1: Scientific Notation

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...

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.

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.

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...

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.

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...

The instructor demonstrates how to convert a number written in scientific notation to a decimal number. An example is given for a number with a positive exponent, and an example is given for a number with a negative exponent.

The instructor demonstrates how to convert a number written in decimal form to scientific notation. An example is given for a number with a positive exponent and an example is given for a number with a negative exponent.

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.
