**Integers Adding and Subtracting**

By: Micheal Stewart

2
**The objective is the students will add and subtract integers with 75% accuracy using manipulatives.**

3
A very effective approach to adding and subtracting integers is to use colored tiles or colored disks.

4
The reason I use red and black disk is because red generally represents positive and black represents negative with most wiring components.

5
**Here is an example of how the colored disk can be used when adding integers.**

6
**Let the red disk represent the positive integers and the black disk represent the negative integers.**

7
**If we add 5+(-4) using our disk we can get a visual and tactile understanding of integers.**

**If one black disk cancels out one red disk, how many red disk are left**

If one black disk cancels out one red disk, how many red disk are left? ONE! The answer is positive 1.

10
**The use of colored disk can be an effective manipulative when introducing integers to students.**

11
**The disks give the students a visual concept of adding and subtracting integers.**
