2.2 and 2.3 Subtracting Integers

Focus Question:  How do you determine whether the final result with increase or decrease when subtracting integers?

In this lesson, we will explore how to use models to subtract integers.  We will also look at how addition and subtraction are connected to one another.

Step 1:  Determine each of the differences from the two different sets.  If you need help, remember to look back at the "subtracting integers" video on the previous post.

Step 2:  Look at the results from the two different sets of differences and try to fill in the blanks below based on the patterns from above.  I'll give you a hint....use "Set 1" to answer the first two bullets, and use "Set 2" to answer the last two bullets.

Step 3: Watch the slideshow below to help you discover the connection between addition and subtraction when it comes to integers.  The statements above will also help.
