What’s in the Mailbox Integer Lab (teacher will give directions)

Today’s lesson... What: Introduction to integers Why: To introduce integers, identify real-life applications, compare/order integer numbers, and study the absolute value of numbers.

What is an integer? Integers include the _____________________ whole numbers, the positive whole numbers, and zero. negative

Real-life Applications:

Identifying positive/negative numbers: Place the following numbers on the below number line: ½ /

Comparing positive /negative numbers: Place a > or a < in the following blanks: 5 _____ -8-1 _____ 0 -1 / 2 _____ _____ _____ _____ -9 > > > < <<

Ordering positive/ negative Numbers: Order the following from least to great: / /451/4 1. Order the following from greatest to least: , -4.5, -1/2, 0, 3, 5 ¼ 7, -7, -7.5, -8, -8.5, -9

Absolute value: Absolute Value measures ___________________ from ________________ on a number line. Absolute value is ALWAYS __________________ because distance ALWAYS has value!! Example: Model the absolute value of 3 ( |3| ) on the below number line: distance zero positive The SYMBOL for ABSOLUTE VALUE is | | ! 0

Evaluate: |9|| -4|-|15| | -3 / 4 | - |- 28| |-6| + | 5| | || | 94-15¾ WHY IS ABSOLUTE VALUE ALWAYS POSITIVE?? Because distance ALWAYS has value!!

END OF LESSON The next slides are student copies of the notes for this lesson. These notes were handed out in class and filled-in as the lesson progressed. NOTE: The last slide(s) in any lesson slideshow represent the homework assigned for that day.
