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 - 2,    great discussion questions,  but these ideas will be used throughout the rest of the practice problems.   I didn’t do a video for these questions.

Question 22,    I was a little bugged that the textbook didn’t really acknowledge all the work that might have been needed to actually answer this question!  So I quickly wrote a (not elegant) program to randomly do calculations and see what the results were.   You can watch THIS VIDEO (short) if you are interested.

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!
