Unit 2 Powers and Exponent Laws

Lesson 924 Exponent Laws I

Focus

The FOCUS section introduces the main concept that will be covered in the lesson.

TEXT Page 73

Read/Work through the  Focus  section at the top of page 73 in  your textbook.

Investigate

Investigate an idea or problem, with a partner if possible.
The investigation provides the background for the ideas presented in the lesson.

TEXT Page 73

Read/Work through the  Investigate  section on Page 73 in your textbook.

There isn’t really any easy way to DO this investigation, since your results will be different from mine 
(rolling dice is random!)

You can use this ONLINE dice roller if you like,  set it for three dice, and use the first one as your red die (the base), and the second two as your blue dice (the exponents)

Do your best to actually do the investigation,  or...   actively watch me do it in the video.

Practice Problems

Doing Practice Problems

Practice problems reinforce the math presented in this lesson.

•	Work through the practice problems for this lesson.
	These problems are for practice, you don’t need to hand them in!
	(your teacher may assign specific questions for you to complete)

•	Use the answers in the back of the book to CHECK YOUR WORK!

•	If you make a mistake, TRY TO FIX IT!

•	If you need help or want more information, view the video solutions provided.

•	If you still need more help,  CONTACT YOUR TEACHER!

Types of Practice Problems

Discuss the Ideas invites you to talk about the math.
If possible share your thoughts/ideas/answers with another person.
If you can help them understand, then you likely have good understanding yourself.

Check questions require basic understanding of the ideas of the  lesson.

Apply questions will require you to dig deeper for a solution.

Take It Further questions offer enrichment and extension.

Notes

Questions 1 - 3,    great discussion questions!  but... all these ideas were covered in the lesson.
I didn’t make videos for these.

Question 21 - 23,    great questions, but IMHO they go way beyond what I would expect a Math 9 student to be able to do.
I didn’t do a video for Question 23.

Video Solution Links

Check your work for every problem you do!
If you make a mistake,  try to fix it!
Use the video solutions for more information.
If a problem still doesn’t make sense, ASK YOUR TEACHER FOR HELP!
