Transcript of Scientific Notation

Objectives: You will learn to evaluate numbers in scientific notation and to learn how to calculate with
scientific notation. Scientific Notation Standard Notation You can change expressions from scientific notation to
standard notation by simplifying the product of the two factors Exploring Scientific Notation 5 California Content Standards Read, write, and compare rational numbers in scientific notation (positive and negative powers of ten), compare rational numbers in general. Writing in Scientific Notation Write in scientific notation.
73,000,000 move seven places
to the left. Scientific Notation provides a way to write numbers
using powers of ten. You write a number in scientific
notation as the product of two factors. 73,000,000= 7.3x10 7 Write each number in standard notation

9.5 x 10
9.500 write zeros while moving the
decimal point. 3 Rewrite in standard notation = 9,500 4 x 10 5 x 10 3 = 5 x 10 2 = ________________ 5 x 10 - 4 = 0.0005 5 x 10 - 3 = 0.005 5,000 = 50,000 500 5 x 10 - 2 = 0.05 7. Look for and make use of structure 1. In what was does this problem connect to other mathematical concepts? 2. What patterns do you find in negative and positive exponents of scientific notation? 6. Attend to precision What would be a more efficient strategy? 1. 2. What mathematical terms apply in this situation? Standards for Mathematical Practice Standards for Mathematical practice Standards for Mathematical Practice Standards for Mathematical Practice 5. Use appropriate tools strategically. 3. Construct viable arguments and critique the reasoning or others. 1. What is the same and what is different about the negative and postive way of scientific notation? 2. How do you test whether your approach worked? 1. What mathematical tools could we use to visualize and represent the situation? 2. What estimate did you make for the solution?
