•The objective is the students will add and
subtract integers with 75% accuracy using manipulatives.
•A very effective approach to adding and subtracting integers is to use colored
tiles or colored disks.
•The reason I use red and black disk is because red
generally represents positive and black
represents negative with most wiring components.
•Here is an example of how the colored disk can be used when adding integers.
•Let the red disk represent the positive integers and
the black disk represent the negative integers.
•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? ONE! The answer is positive 1.
•The use of colored disk can be an effective
manipulative when introducing integers to
students.
•The disks give the students a visual concept of adding and subtracting integers.
