This document provides information about MAP testing schedules, online course materials, and goals for an exponential notation lesson. It outlines that MAP tests will be given on Tuesdays for reading, Wednesdays for math, and Thursdays for language from 9:00am or 2:00pm. Students must have a working webcam. The document schedules exploration of signs for negative bases raised to odd and even powers and wraps up by explaining the usefulness of exponential notation for recording scientific values.

1. HOUSEKEEPING
MAP testing: Two Sessions Per Day (9:00am or 2:00pm)
Tuesday – Reading
Wednesday – Math
Thursday – Language
* Must have a working webcam!!!
Unit 1 is now open (New lesson will open each day)
Use course mail, NOT Gmail
Notebook Recommended!!!!

2. EXPONENTIAL
NOTATION

3. GOAL FOR TODAY…….
Goal:
 Know what it means for a
number to be raised to a
power and how to
represent the repeated
multiplication symbol
 Know the reason for some
bases to require
parentheses
Agenda:
 What is
exponential
notation?
 How do you
determine the
sign of the
result?

4. Exponential Notation
In general, for an number x and any positive integer n
Base
Exponent
Example: 35=243

5. Use parentheses where the base is either
fractional or negative.

8. Exploration
When a negative number is raised to an odd
power, what is the sign of the result?
When a negative number is raised to an even
power, what is the sign of the result?

15. WRAP UP
It’s over
already : (
Why should we bother with
exponential notation? Why
not just write out the
multiplication?
Exponential notation is used
for recording scientific
notation of very large or very
small quantities. It is
indispensable for the clear
magnitude of a number.
