Ladder Model

Factor Tree

Prime factorization- factorization containing only prime numbers.

Factorization- Composite numbers can be expressed as product of two or more whole numbers greater than 1.

Composite Numbers

Numbers in which there are more than two factors or positive divisors. (ex) 4, 8, 12, 16

Prime Numbers

Numbers in which there are only two factors or positive divisors. (ex) 2, 3, 5, 7

Divisibility

Divisibility rules

If b l a, then b is a factor, or divisor, of a, and a is multiple of b.

Multiplication and Division of Integers

Order of Integers

Order of Operations on Integers

The order of operations: parenthesis, exponents, multiply/divide left to right/ add/subtract left to right.

Integer Division

The quotient of two negative integers, is a positive integer and the quotient of a positive and negative integer, is negative.

Add and Subtract integers

Integer Subtraction

Properties of Subtraction

Subtraction Using Adding the Opposite Approach

SubtractionUsing the Missing Addend Approach

Pattern Model for Subtraction

Number Line Model for Subtraction

Charged-Field Model for Subtraction

Chip Model for Subtraction

Uniqueness of the Additive Inverse

For every integer a, there exists a unique integer -a, the additive inverse of a.

Integer Addition

Absolute Value-The distance between the point corresponding to an integer and 0 is the absolute value of the integer.

Pattern Model- Addition of integers can also be motived by using patterns of addition of whole numbers.

Number Line Model- Always start at zero and move line to first number, then go to second number.

Charged-Field Model- Similar to chips but used the positive (+) and negative (-) charges.

Chip Model for addition-Black chips are used to represent positive integers and negative integers are red.
