1 Unit I – Rational Numbers August 15 - 19
Homework – Study for Vocabulary Quiz Addition and Subtraction Quiz – Thursday I will be absent Tuesday and Wednesday. There will be a substitute teacher. Be on your best behavior. Quizlet

2 Activating Strategy - Warm-up August 15, 2016
Solve the following: 3/ /5 = 1/ /3 = 3/ /5 = 3/ /10 = 3/ /11 =

3 Vocabulary Absolute Value: The distance between a number and zero on the number line. The symbol for AV is shown in the equation: │ -8 │ = 8 Integers: The set of whole numbers and their opposites (… -2, -1, 0, 1, 2, …) Opposite numbers: Two different numbers that have the same absolute value. Example: 4 and -4 are opposites

4 More vocabulary Positive Integer: an integer that is greater than zero
Negative Integer: an integer that is less than zero Rational Number: the set of numbers that can be written in the form A/B, where A and B are integers and b is not equal to zero

5 Absolute value The distance from a number to zero on a number line.
Absolute values are ALWAYS positive.

6 Addition - PRINT SAME SIGNS (both signs are positive or both signs are negative): Add the numbers and keep the sign – 2 positives stay positive, 2 negatives stay negative DIFFERENT SIGNS (one positive and one negative): Subtract the small number from the larger number Keep the sign of the larger number – if positive number is larger, answer is positive; if negative number is larger, answer is negative

7 Addition Song Same sign add and keep Different sign, subtract
Keep the sign of the larger number Then you’ll be exact (To the tune of Row, row, row, your boat)

8 Addition on a Number Line
Always start at ZERO Draw your arrow from 0 to the first number in the equation. Always start your second number where the arrow for the first number ends. Draw the second arrow the absolute value of the number.

9 Subtraction Keep Change Change (KCC)
Keep the sign of the first number – keep it as it is Change the problem from subtraction to addition ( - becomes +) Change the sign of the second number – positive number becomes negative, negative number becomes positive Use the rules of addition (you changed it to an addition problem!)
