Unit 2 Integers

Lesson 2.1 Representing Integers

Getting Started

There are a few things to cover BEFORE we actually get into the lesson.

You will be using Integer Tiles for all of the lessons in Unit 2.

There are lots of places online where you can find virtual tiles that you can use, but some of them are more complicated than what we need.

Your teacher may also have something specific they want you to use.

I will be using Google Docs and a set of virtual tiles for my lessons.

You can find the link to this document below.

Focus

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

Use coloured tiles to represent integers.

Video Tutorial

Explore

Explore an idea or problem.
The exploration provides the background for the ideas presented in the lesson.

TEXT Page 52

Read/Work through the  Explore  section on Page 52 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.

To zero in on what I think is the idea of this question...
a)  How many different integers can you represent using any 9 integer tiles
b)  How many different integers can you represent using any 10 integer tiles

Demonstration

You can use this demonstration to do this exploration.

You can change the number of red and yellow tiles,  and view the result using the “show” checkbox.

Video Tutorial  (using the demonstration)

(Note,  I added the “+“ sign to the positive numbers, after I made the video...)

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.

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!
