Lesson 1.1 SI Measurement

Focus

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

TEXT Page 8

Read/Work through the  Focus  section at the top of page 8 in  your textbook.

Do your best to answer the questions given in this section, but no worries... this will all be covered in the lesson.

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 8 - 9

Read/Work through the  Investigate  section on Pages 8 - 9 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!

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  Estimate and Measure Using SI Units

TEXT Page 11

Work through Example 1 on Page 11 in your textbook.

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 comments 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.

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!

NOTES!
Some of these questions seemed to be so vague and difficult, that the time spent tackling them would not be “value added”  (my personal opinion).   I have NOT created video content for the following questions for that reason.  If your teacher really wants you to do them,  hopefully they will be able to provide you with the support needed to make them worthwhile.
