Integers Integers Adding and Adding and SubtractingSubtracting

•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.

•THE END
