Scientific Notation II: The Mantissa

How do you write a number in scientific notation? The handout and video provide an explanation on how to convert from standard form into scientific notation and vice versa. The resource also contains a short discussion about choosing...

Writing a number is all in the notation. The resource introduces the class to scientific notation. Pupils learn the process of taking a very large or small number in standard form and write it in scientific notation. To practice,...

Would you rather have a million dollars or 1 x 10^6 dollars? To find the answer to this question, class members first complete an assessment task converting numbers between decimal notation and scientific notation. They then take part in...

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.

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

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.

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...

Large numbers don't have to be a drag to work with. The video shows viewers how to estimate a large product of numbers. This involves first converting the numbers to scientific notation and then applying multiplication.

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.
