Integers Adding and Subtracting Integers Adding and Subtracting By: Micheal Stewart
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.

What two numbers will give you a product of 64 and a quotient of 4?
To help students visualize abstract concepts Introduce a new topic; students then can discover the algebra rules instead of being told by the teacher.
FRACTIONS Lets draw a rectangle, and divide it in two equal parts...
Simplifying Rational Expressions We are trying to get common terms to factor ( cancel ) to = 1. You might have to distribute or FOIL to get started. ALWAYS.

How to subtract integers. Why change to addition problem Subtraction is the opposite of addition So we make things opposite.
Goal: By the end of the lesson, students will be able to find the slope of a line from a graph.
SYSTEMS OF EQUATIONS. Substitution Method Ex. 1:2x + y = 15 y = 3x We have been using the Substitution Property in our proofs. Now we are going to use.
Consecutive Integers Consecutive Integers are integers that follow one after another. Example 1: are consecutive integers.
Subtracting Polynomials. Lets review Copy the following expressions and then write the opposite of each one. 1. 2y x 2 +5x m 2 -m+3.

Introduction, Computers work by following a series of steps. Computers work by following a series of steps. These steps organize objects (set of variables)
POLYNOMIAL FUNCTIONS A POLYNOMIAL is a monomial or a sum of monomials. A POLYNOMIAL IN ONE VARIABLE is a polynomial that contains only one variable. Example:
The Pigeon hole problem. If k+1 objects are placed in k containers then one container must contain at least 2 objects Obviously!
