Video Tutorial

Investigate

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

TEXT Pages 268 - 269

Read/Work through the  Investigate  section on Pages 268 - 269 in your textbook.

A list of materials  you need for the Investigation is given in the side bar.

Your work will be a lot more efficient if you PLAN for and GATHER these items BEFORE you start the Investigation!

You may not have other students to work with.  
No worries!  
If you are working on your own,  answer the questions, AS BEST YOU CAN, before you view the Tutorial that follows.
Once you have done that,  view the video for help with this section.

ONLINE Graphing Stories

Optional,  but good stuff

If you have the opportunity,  and you want a chance to explore some stories and see a GOOD graph that results from the story, check out THIS WEBSITE.   They have done a great job of connecting a video with a graph that describes the action, and it’s not so subjective....

There is a whole set of activities set up to help with this idea of a graph story.   
Desmos Function Carnival.
Your teacher might have you do it as a class.   
HERE IS ONE video where a teacher works through one of the activities in video form.  
Not as good as doing it yourself,  but potentially still really helpful.

Link the Ideas

Link the Ideas summarizes the math in the lesson.
A presentation of ideas connected to the lesson focus.

Examples

Examples will give you TOOLS for solving problems, and also show you that there may be different ways to approach a question.

Example 1  Interpret a Graph

TEXT Page 271

Work through Example 1 on Page 271 in your textbook.

No video here,  the textbook description of the graph is (hopefully!) straight - forward.

Your Turn

YOUR TURN gives YOU the chance to try to do a problem ON YOUR OWN,  using the example as  a model.

Use the Video Tutorial for help, or to check your work, BUT... you should do your best to do this question ON YOUR OWN FIRST!

Key Ideas

Key Ideas summarizes the main new concepts of the lesson.

•	Carefully read through each of the bullet points in this section.

•	If you are unclear about any of these ideas,  ASK YOUR TEACHER FOR HELP!

Check Your Understanding    (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

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

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

Extend questions offer enrichment and extension.

Create Connections questions connect the math to everyday contexts.

Mini Lab (optional)  your teacher may or may not have you do these.

Notes

Question 4,    I didn’t do a video here,  the answer is subjective, and the textbook answer is clear and provides good examples.

Question 16,    I didn’t do a video here, great question but a lot involved if you do it well.  More of a project kind of question!

Question 17,   It would be great to have all the technology to be able to do this activity...
I did do a video, and discussed what (generally) the motion would have to be to produce the graphs shown.
It would be helpful to do a thought experiment first.... (how would I create those graphs IF I had the setup in the question....)  , and then view the video to see what my thoughts were.

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!
