Lesson 1.2 Imperial Measurement

Focus

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

TEXT Page 22

Read/Work through the  Focus  section at the top of page 22 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 22 - 23

Read/Work through the  Investigate  section on Pages 22 - 23 in your textbook.

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

The BEST tool  for this investigation (if you have it available) is a TAPE MEASURE that has inches and feet.

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, then move on to the next section.

All these ideas will be covered in the NOTES (Link the Ideas) for this lesson.

Link the Ideas

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

TEXT Pages 23 - 24

Read/Work through the  Link the Ideas  section on Pages 23 - 24 in your textbook.

Measuring...?

I saw this come up today...   some of the basic skills we assume people know  (like measuring stuff using a measuring tape...)  are rapidly being “out-sourced” to technology...

Tape Measure demonstrations

For all the demonstrations that follow,  assume the length of measurement is an INCH.
The demonstrations are for practice, they are NOT to scale!

Vernier Calipers

Here are some pretty detailed instructions on reading an IMPERIAL vernier caliper.
IMHO,  this shouldn’t be something you HAVE to know, it’s obscure,  and requires more memorizing of steps rather that learning “math” content.
But this is for your TEACHER to decide.

Referents  Imperial  (a summary)

1 inch   One inch is roughly the distance from the middle thumb joint to the tip of the thumb.

1 foot   A men’s size 14 shoe is 1 foot.
	foot long sandwiches at Subway
	1 foot from elbow to wrist  (depends on age and size of person)
	There are 12 inches in 1 foot

1 yard   a little less than 1 metre
	distance from your nose to the tip of your outstretched arm
	There are three feet in one yard

1 mile   there are 5280 feet in a mile	
	there are 1760 yards in a mile

Examples

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

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
I really would like to feel that doing a question is VALUE ADDED.
So,  there are a few questions I didn’t do....
I didn’t do Question 5 (see the answer in the back of the book...)
I didn’t do Question 6 (see the answer in the back of the book...)
I didn’t do Question 12  (anyone still have CD cases or MP3 players around...?)
I didn’t do Question 17  (though the information about bed sizes is readily available on the internet,  and making scale diagrams is a useful thing to do)
I didn’t do Question 19
