2 TEKS Objective6.1cStudents will use integers to represent real-life situations.
3 PurposeThe learner will synthesize negative numbers and positive numbers into daily life.
4 Have you ever sacked the quarterback Have you ever sacked the quarterback? Have you ever seen a pass completed for 50 yards?That’s using Integers!
5 Integers Integers are positive and negative numbers. Positive numbers are greater than zero on a number line. Ex: ½, 1, 99 2/7, 10,978,457,896….Negative numbers are less than zero on a number line. Ex: -1/2, -1, -99 2/7, -10,978,457,896…Zero is not positive or negative (Remember, it is nothing!!!)
6 Integers on the Number line For every positive number there is a negative number.A number line is continuous in both directions.-2-1.5-1-.5.511.52
7 Guided PracticeWrite the number sentence represented by the word problem.An elevator started at the first floor and went up 18 floors. It then came down 11floors and went back up 16. At what floor was it stopped?Ex: went up 18 = +18down = -11up = +16(+18) + (-11) + (+16)At midnight, the temperature was 30F. By 6:00a.m., it had dropped 5F and by noon, it had increased by 11F. What was the temperature at noon?Ex: Temperature was 30F = +30Dropped 5F = -5Increased 11F = +11(+30) + (-5) + (+11)
8 Independent Practice Write the integer for each situation. A gain of 6 lbs ft below sea levelA deposit of $ s before blastoffScore 10 points 8. A withdrawal of $145 years ago A debt of $122 km below the surface 10. A gain of 9 yds
9 Conclusion Students use integers to name situations. Introduction before addressing integers with operations.Now you’re ready to learn more about integers! Go to the following site and do the activities.
