Lesson 86 Identifying Transformations in Tessellations

Focus

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

There isn’t a Focus section in this lesson.

Investigate

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

The website you can link to below allows you to see and experiment with pattern blocks,  but it’s not great.
Printing a set and working with those is also not ideal, but  might work better for the Investigation.

The textbook tells you to create your tessellation on isometric grid paper.
Here is a link to an isometric grid you can download/print.

TEXT Page 471

Read/Work through the  Investigate  section on Page 471 in your textbook.

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.

IF you want to do the investigation but also want some feedback on your work,  use a square and a triangle to create your tessellation.
That’s what I used so you can compare your work with mine.

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 2,    I answered this when I did Example 2.

Question 10,    it would be great if you did this!  Show your teacher!   I didn’t do a video for this one.
Do a search for “digital quilt design”,  and you will see some amazing patterns.

Question 11,     I didn’t do a video for this one.
Good question, but repeated information, and not a specific answer.

Question 12,    I didn’t do a video for this one.
Good question, but repeated information, and not a specific answer.

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!
