Performance Task # 1 Task 2 Full Description: You have given the scuba divers a course in how deep they can go below sea level before the pressure becomes dangerous to their lives, they have asked you to help them figure out how fast they can ascend to the surface. Role: You are a scuba diving instructor. Audience: Students in your class. Situation: You are a scuba diving instructor and your class needs instruction on how fast they can return to the surface. Product : Construct mathematical equations to model scenario Which standard(s) (priority/supporting) will the task address? 7. NS.2. Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as ( 1)( 1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real- world contexts. b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then (p/q) = ( p)/q = p/( q). Interpret quotients of rational numbers by describing real-world contexts. c. Apply properties of operations as strategies to multiply and divide rational numbers. What essential Question(s) and corresponding Big Idea(s) will this task target? How is the number system used to fit different situations? Why do we need to agree on a specific order of operations? How does changing the order of operations affect the outcome when simplifying an expression? How is the order of operations like a recipe for chocolate cookies? Numbers can represent quantities, relationships, location, and position. Rational numbers have multiple interpretations, and making sense of them depends on identifying the unit. The concept of unit is fundamental to the interpretation of rational numbers. The concept of unit is fundamental to the interpretation of rational numbers. One interpretation of a rational number is as a part-whole relationship. One interpretation of a rational number is as a quotient. Recognize how addition, subtraction multiplication, division, powers, parentheses and roots of numbers effect the magnitude of the result

Grade 7 Unit 1 Task 1: Scuba Diving Down Goal: Arrange integers in order. Role: You are a analyzing a Julie Brown Anderson s dive. Audience: Reader of article. Situation: You are interviewing for a job at a sports magazine. You have been asked to comment on the scuba diving techniques of certain divers. Product: Brief article describing the dive of Julie Brown Anderson on 5/9/12. Standard: CCSSM 7.NS.1 & 3 Assessment: You will be assessed using the attached rubric. Cold Water Diving: It s all relative how cold is cold?!? By Julie Brown Anderson On June 4, 2012 Posted in: Scuba Diving Below is a graph of one dive by diver Julie Brown Anderson. She has charted her depth and temperature of the water she was in and compared them to time. The x-axis is the time she is underwater. For example, 3 00 means she was under water for 3 minutes and 27 00 means she was under water for 27 minutes. The y-axis on the left shows the number of feet below the surface (be careful: the lines going horizontal do not match up with these!!). The y-axis on the right shows the temperature of the water she was diving in at that time. - - - - - Source: http://scubadivergirls.com/scuba-diving-2/cold-water-diving-its-all-relativehow-cold-is-cold/ Grade 7 Unit 1
Task 1: Scuba Diving Down Student Name: Date: Teacher: Section: You are interviewing for a job at a sports magazine. As part of your initial interview you have been asked to analyze Julie s dive. You will need to collect the data from the graph above. : 1. Complete the table of the 3 types of data. a. Estimate the depth to the nearest foot b. Estimate the temperature to the nearest tenth of a degree Time (mins) Depth (ft) Temperature ( F) 0 3 6 9 2. Construct a number line to graph the integers in correct order from the depth column.
3. You have decided to give some scuba divers a crash course in how deep they can go below sea level before the pressure becomes dangerous to their lives, approximately 40m. Since you are the expert, the scuba divers present various scenarios for you to explain. For example, if a diver is 7 feet below sea level and descends 85 feet, where is the diver relative to sea level? Is she safe? You are to use your number line and table to write addition and subtraction equations, write and draw a diagram for four different situations depicting how far a scuba diver can go below sea level to study marine life, and explain your solutions. Write 2 addition equations and 2 subtraction equations. (Hint: you must convert to find the maximum depth in feet. 1m is approximately 3.3 feet) 4.Describe what happened during the interval of 0 minutes to 3 minutes, the interval of 3 minutes to 31 minutes, and the interval of 31 minutes to 39 minutes.
Grade 7 Unit 1 Task 2: Scuba Diving: How Fast UP? & What about the air? Goal: Create 4 number sentences showing multiplication and division of positive and negative numbers. Role: You are a scuba diving instructor. Audience: Students in your class. Situation: You are a scuba diving instructor and your class needs instruction on how fast they can return to the surface. Product: 4 number sentences as examples for your students. Standard: CCSSM 7.NS.2 & 3 Assessment: You will be assessed using the attached rubric. Description: Since you have given the scuba divers a course in how deep they can go below sea level before the pressure becomes dangerous to their lives, they have asked you to help them figure out how fast they can ascend to the surface. Since you are the expert, the scuba divers present various scenarios for you to explain. First, you must lead them to find the maximum speed at which they can ascend. We know from the last class that the maximum depth of a dive for recreational divers is approximately 130 feet. At a safe speed it should take you at least 4 minutes and 20 seconds to get to the surface. What is the safe ascending speed? (Round to the nearest foot.) Second, Now the group presents you with scenarios. 1. How long will it take for a diver to return to the surface from a depth of 98ft? 2. A diver decided to ascend going slower than the maximum return rate. She goes at 20ft/min from a depth of 123 feet below surface. How long will it take her to return to the surface? 3. A Navy SEAL is returning to the surface from a depth of 165 feet. The Navy uses an ascent rate of 60ft/ minute, how many minutes will it take for the SEAL to return safe to the surface? 4. A diver off the shore of Malibu, California is 112 feet below and realized she needs to meet her friend in 13 minutes. The boat is 9 minutes from the dock. Can she make it? You now have to show them the solution to each scenario.
Third, your class is now concerned about diving time. You now instruct the class on using an air tank. The standard size tank is 100 cubic feet and lasts about 50 minutes. So you present the class a scenario. A. Peter filled up only ¼ of the 100-cubic feet air tank because he was short on money. He used ½ of the air in a quick dive with some friends. How long was he under water? B. He decides to get air at this point to fill his tank, how many gallons will he be adding to fill the tank? C. If air cost $0.50 a cubic foot how much did he pay for the air? You now have to show them the solution to each scenario.
