Investigate

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

TEXT Page 110

Read/Work through the  Investigate  section on Page 110 in your textbook.

You may not have a partner to work with.  
No worries!  
You can do this activity on your own.
Do your best to answer the questions, then watch the Video Tutorial for help or to check your answers.

HINT!   You could use fraction circles (pies) to do this,  but it’s easier to use grid paper and rectangles.
(think of a rectangular pie)

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

Work through Example 1 on Page 111 in your textbook.

Note!   I don’t imagine students using these lessons will have access to PATTERN BLOCKS...?
A great manipulative,  but I will do this using a GRID MODEL since I believe it’s the easiest of the models, and can be created using simple grid paper.

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

Discuss the Ideas invites you to talk about the math.
If possible share your thoughts/ideas/answers with another person.
If you can help them understand, then you likely have good understanding yourself.

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

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

Take It Further questions offer enrichment and extension.

Notes

Question 1,    We didn’t use Pattern Blocks, and if you wanted to... it wouldn’t work, I don’t believe there is a block for (1/16)

Question 4,    I think I’ve given the answer to this in the video for Example 3, as well as the video for Question 3

Question 9,    “create your own”,   so I didn’t make a video.   I think there are plenty of other examples to do and see without making up more....

Question 14,    “create your own”,  so I didn’t make a video.  
The product is (4/45)
Okay, my question. .....  
Of all Gwen’s books,  (1/5) of them were in a bookcase in her room so they could be handy. 
Of those books,  (4/9) of them were math books on the TOP SHELF  because she read those most of all. 
What fraction of Gwen’s books were in her room on the top shelf.
