Read, write and represent integers November 11, 2010 Ms. Latimer

Vocabulary Integers – numbers used to represent real life quantities Positive Integers – Integers > 0 Negative Integers – Integers < 0 Opposites – Two Integers that are equal distance from zero Ex: (-3, -2, -1, 0, 1, 2, 3) Words like: profit, increase, gain and above indicate positive integers Words like: loss, decrease, and below indicate a negative integer Ex: 15, -15 are both 15 units away from zero

Write the Integer Represented 1.) a $13 profit 2.) a 20 point decrease 3.) a gain of 9 yards 4.) a withdrawal of $15 5.) a deposit of $10 6.) the opposite of ) 19 feet below sea level

Your Turn: Skill Practice: Write the integer that represents the situation 1.) 20°F below 0 2.) 3 seconds before liftoff 3.) no gain on the 1 st down** 4.) a growth of 2 inches

Graphing Integers on a number line. Graph the following on the number line below: -5, 4, 3, -2.5, 1.5 Let’s try it ourselves…. Some students have an Integer, and we need to put them in order. If you have an integer then head to the front. If you do not have a number you get to move students into position. NO TALKING ALLOWED!

Word Problem: 1.) A scuba diver is 14 feet below sea level. A second scuba diver is 22 feet below sea level. Write an integer to represent the divers’ positions relative to sea level. 2.) Which two opposite numbers are exactly 32 units apart from each other on the number line?
