Today you are going to master the skill of summing integers. First off, please write below the answer to this question:

What are the characteristics of an integer? What makes an integer an integer? Be as specific as possible.

1

What does it mean to "sum" numbers? Can you give an example?

You are going to learn about summing integers today by using integer counters. These are the little red and yellow circles that you saw at the top of the page. Please get 10-15 integer counters each from the high table in the back and bring them to your desk. 

Once you have them, please watch the short video below.

You will need the integer counters and your phone to answer this question.

1. Using the integer counters, create a scenario that models -3 + (- 5). Place your integer counters on a white piece of paper and take a picture. Then upload that picture below.

2. Evaluate -3 + (-5). Write your answer in the space provided below.

Let's incorporate the number line. It's a really useful tool when trying to picture what is happening when you sum integers. Watch the video below to get a feel for it, then continue on to the following questions.

This one's a little tricky! You're going to need to use your whole brain to answer these questions!

Can you write an equation that represents the scenario being modeled on the number line below?

In your digital BIG IDEAS textbook, read page 10 - 11. Write in your notes the definitions to the two words highlighted in yellow. Also, make note of the KEY IDEAS.

According to legend, the Chinese Emperor Yu-Huang saw a magic square on the back of a turtle. In a magic square, the numbers in each row and in each colum, and diagonally, have the same sum. This sum is called the magic sum.

Below you can see a picture of the turtle that the Chinese Emperor saw. Complete the magic square so that each row and each column has a magic sum of 0. Use each integer from -4 to 4 exactly once.

Here is another magic square. Are you up to the challenge of completing it? Fill in the missing boxes.

Uh oh... no magic number. What will you do? Are you up to the challenge of completing it? Fill in the missing boxes.

Now comes the really tricky part. Can you come up with your own magic square? You have to use positive and negative numbers. Go ahead, earn your E and impress me!
