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.

Connect

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

Read/Work through the  Connect  section on Page 435 in your textbook.

Even if you KNOW you are going to watch the video, READING this section is still important.

Getting the same information in multiple ways can help with understanding.

I suspect most students using these lessons will NOT have access to linking cubes.
THIS isometric drawing tool can help you with some of the ideas of this lesson.

Video Tutorial,   using the tool

Examples

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

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 11,    it would be GREAT to do this with linking cubes,  super helpful.   But I didn’t make a video for this one.

Question 15,    here is a link to a site with the same task,  building a “4 - cube” shape.
Depending on how you define different,  the task says there are 15 shapes.
But if you can rotate/flip a shape and make it match, then mathematically, the shapes are the same.
The text says seven different shapes and I agree.

Question 17,    I didn’t do a video for this one,  check the answer in the back for some ideas.

Question 18,    I didn’t do a video for this one.

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!
