PPT-Lesson 1.1 Integers and Absolute Value

Students will be able to use integers to represent the velocity and the speed of an object as evidenced by the class discussion after watching a short video httpswwwyoutubecomwatchvM9NBZJR5tyo. 1. Order the following numbers from least to greatest. . . 15, , -2, , -12, 0, . A dog is standing on a cliff, 35 feet above sea level. A dolphin is swimming 6 feet below sea level. An octopus is moving along the seabed 40 feet below seal level.. Essential Question: How do you compare and order integers?. Key Vocabulary . Integers: all whole numbers and their opposites . Negative Integers: integers less than zero. Positive Integers: integers great than zero. 1. 1. 2.. 3. 4.. Absolute Value Equations. 2. Absolute Value Inequalities. Absolute value inequalities are solved in the same way linear inequalities are solved. . Change the inequality to an equality and solve.. Solve . n . + (. n . + 2) = 14. 9. 6 & 8. Carrie had $32 when she got to the carnival. After riding. 6 rides, she had $20 left. Solve 32 - 6. x . = 20 to find the. price for each ride.. Alg.. If David’s brother is 3 years older, and the sum of their. the Number Line. Comparing Rational Numbers. Integers. MCC6.NS.5: Understand that positive and negative numbers are used together to describe quantities having opposite directions or values.. MCC6.NS.6a: Recognize opposite signs of numbers as indicating locations on opposite sides of 0 on the number line; recognize that the opposite of the opposite of a number is the number itself , e.g., -(-3) = 3.. Equations. AII.4a – The student will solve, algebraically and graphically, absolute value equations and inequalities. Graphing calculators will be used for solving and for confirming the algebraic solution. . http://. www.youtube.com/watch?v=m94WTZP14SA. Colin . Dodds. - Number Types (Math Song) . top. bottom. a. bove sea level . increase. decrease. below sea level . . Positive and Negative Integers. A. Solving an Absolute Value Equation. You have already used graphs and mental math to solve some absolute value equations. For instance:. 8 and -8. This has two solutions:. Solving an Absolute Value Equation. Absolute Value Inequalities, Absolute Value Conjunctions, Absolute Value Disjunctions, Negative Numbers and Absolute Value. Absolute value inequalities are either conjunctions or disjunctions. The reason for this is evident if we draw a number line and indicate the absolute value of each number. . Student Expectation. 7. th. Grade:. 7.1.2C. Use . models, such as concrete objects, pictorial models, and number lines, to add, subtract, multiply, and divide integers and connect the actions to algorithms. . http://. www.youtube.com/watch?v=m94WTZP14SA.

Gaussian Integers and their Relationship to Ordinary Integers Iris Yang and Victoria Zhang Brookline High School and Phillips Academy Mentor Matthew Weiss May 19-20th, 2018 MIT Primes Conference GOAL: prove unique factorization for Gaussian integers (and make comparisons to ordinary integers) Absolute and relative white cells count Absolute value (leukocytes/mm 3 = Total leukocyte count ( cells/mm 3 X Relative value(%) Example: Total leukocyte count = 6000 Segmented forms (relative no.) = 50 % Lesson Topic: The Mean Absolute Deviation (MAD) Lesson Objective: I can… I can calculate the mean absolute deviation (MAD) for a given data set. I can interpret the MAD as the average distances of data values from the mean.
