This document provides information about scientific notation. It begins with examples of writing very large numbers in scientific notation by putting the first significant digit, followed by a decimal point if needed, and then an exponent of 10. Students are then given practice problems converting numbers between standard form and scientific notation. The document concludes by having students check their work and correct any mistakes.

12. BEFORE YOU LEAVE
Find the mistakes and write the correct answer for the
problems that I completed.
1.) 52,000 ANSWER: 52 X 103
I wrote 52 because you always put the decimal after where the
numbers end. I wrote 10 to the power of 3 because there are
three zeros in standard form.
