Class Reminders for new kids to class and review for returning students
1. My web site “teacher calendar” has notes, homework, answers keys, and DYGI practice
2. HW is graded considering: • Completed by due date• Completion WITH WORK SHOWN• Completed in pencil• Graded in red pen…I want a check next to every correct problem and an X on every problem
you missed….it is up to you how you want to correct the problem
3. TC can earn up to 10% - follow directions on form – if incorrect “corrections” – you may not be earning all 10 % back…Get in by the due date stamped on original
4. Retests must be done by due date stamped on the original test. Earn up to a max of 70%
5. Tips for success in this class:• Pay attention, take thorough notes, and ask questions during lessons• Study for first set of quizzes and tests so you don’t get on redo time-consuming cycles• Do HW and THEN check answers. Rework problems missed.• Ask questions in class or tutoring- PRIOR to quiz day - on concepts you are struggling with
6. Stay in your assigned seat until the bell! IN SEAT!!!!!!!!
7. Bathroom pass may be used before or after the lesson. One at a time out of the room!
8. HW, Quizzes, and tests are to be worked in pencil! Your notes are up to you! (-10 or redo)
Day 1 : Laws of Exponents
ReviewBook sections 7.1 and 7.4
a0 = 1 b-1 = (am)(an) = am + n
= am – n (ab)m = ambm
Roots and Rational Exponents
If
Then
New Law: Rational Exponents
You may choose whether to find the root
or the power first!

You try on your marker board
The teacher will show you 10 problems on the smart board. The student will rearrange the form of the equation from:
Exponential to Radical
or
Radical to Exponential
on the student’s marker board.
