Use the comment section below to ask questions or respond to questions asked by a classmate.  I will be checking the comment section at 8:30 each evening the week of the test to answer questions as well.

Helpful Study Tips:

• Look over/correct Quizzes
• Re-watch videos from this unit. (They can all be found here.) ONLY WATCH the videos you feel you need to review.  DO NOT WATCH ALL OF THE VIDEOS AGAIN!!
• Look over your WSQs and Notes we took as a class 
• Check over/do your study guides.
• Use your textbook to work on sample problems (the answers to the odds are in the back of the book) on areas you are concerned about. Chapter 5
• Try out some of the problems on the Jeopardy review game.
• Participate in the Online Group discussion in the comment section below.
• Ask Mrs. Sopko if you have any further questions in the comments section below.

Test Structure:

• There are no multiple choice questions on the test.  
• The test is set up very similar to the quizzes.  You will have to compute some answers and you will need to explain some of your answers.

Complex Fractions

Watch this video as many times as you need. WSQ in your notebooks.  

W = Work out any problems assigned during the video in your notes.

S = Summarize the video.  This can be done using bullets.  List at least 3 things you learned from this video or important things to remember about this lesson.

Q = Question you have or a question someone else might have about the information in the video. This can also be a question that sparks discussion or causes other to think about the topic more deeply.

Summary Questions:

1. How do you turn complex fractions to unit rates?
2. How do you divide fractions?
3. How is converting complex fractions to unit rates similar to dividing fractions?
