Integer+Operations

Below are two sketches that I did when I first learned Geogebra. I adapted them from manual. I hope you enjoy using them in your classes. You can use this accompanying document for students to work on in class

=Integer Addition = One of the most common mistakes in mathematics is a students ability to simplify numerical expressions involving positive and negative numbers. Below you will find a sketch that students can manipulate to help answer some of the following questions: media type="custom" key="29504509"
 * 1) When adding numbers with different signs, how do you know what the sign of the sum will be?
 * 2) How are adding two positive numbers similar to adding to negative numbers? How are they different?

=Integer Subtraction = This sketch is the accompanying sketch to **integer addition.** As an educator, I know that it can be frustrating when students mix up the signs when adding or subtracting integers. The goal for students in the activity is for them to determine sign of subtracting positive and negative integers together.
