Focus

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

TEXT Page 56

Read/Work through the  Focus  section at the top of page 56 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 Pages 56 - 57

Read/Work through the  Investigate  section on Pages 56 - 57 in your textbook.

I don’t suspect that many students will do Question 3b, and Question 4 is discussion based .
Your teacher will let you know whether you need to do these questions or not.

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.

Converting

The textbook often “teaches” things, using examples.
Nothing wrong with that, but these three (short) video clips TEACH some important ideas more directly.

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 6,  there are many websites to document this amazing quilt.  Here is a link to one of them (OPTIONAL)

Question 13,   the text asks YOU to choose an area in Northern Canada.  If you are interested in the process,  let me know and I can create a video outlining the process.  I did a quick search trying to find a “nice” map with a scale that was easy to read, but couldn’t find one right away,  so I skipped this question.

I didn’t create videos for Questions 14 - 16, the text has reasonable answers, and they are quite discussion questions and subjective.

Video Solution Links

Check your work for every problem you do!
If you make a mistake,  try to fix it!
