|Assessment Evidence (Stage 2) |

|Performance Task Description |

|Senior Tyler Smith budgets $1100 for a 4 day trip to Orlando. He expects to pay $600 on travel and lodging. The price per ticket for theme parks is $60 and he expects to pay an average of $20 per meal. |

|If T represents the number of tickets and M represents the number of meals, then give an inequality to represent the feasible options. |

|Using the inequality above, solve the inequality for M. |

|If he eats at least one meal per day and visits a minimum of 3 parks, write two inequalities one for the number of meals he can eat and one for the number of parks he can visit. |

|Using the three inequalities graph the feasible region (T is the independent variable and M is the dependent variable). |

|Are the maximum numbers of meals and tickets reasonable? |

|Is it possible/reasonable to visit 6 parks and eat 5 meals? |

|What is the best scenario (number of tickets, number of meals) for Tyler? Explain your suggestion. |

|Goal |To create travel suggestions for a high school senior to visit Orlando over 4 days on a budget of $1100. |

|Role |To create a travel package for the customer within their budget. |

|Audience |The customer visiting Orlando on a fixed budget. |

|Situation |The customer has $1100 to spend on a 4 day trip to Orlando and wants to visit multiple parks which cost $60 and has appropriate spending money for meals which cost |

| | |This activity consists of a game where assessments are placed at each of 6|between the lines. Graph the lines and compare |

| | |stations (or more with a group larger than 24). Participants are expected |their graphs. |

| | |to answer the questions. Answers are placed on colored paper (keyed to | |

| | |each station) and turned in before moving to a new station. The color | |

| | |coding is used to identify which station the answers come from. This is a | |

| | |timed activity where each group has the same amount of time at each | |

| | |station to work on the questions. Suggested time is 7 minutes per station.| |

| | |The winner of the game is the group with the most correct answers. An | |

| | |important part of this activity is the debriefing of the game. The purpose| |

| | |of the game is to inform assess the students’ prior knowledge. Point out | |

| | |the scoring grid and how to keep track of each group’s score. It may be | |

| | |helpful to have each group write their names on a piece of paper and put | |

| | |that paper on the front table. As each timed session finishes the group | |

| | |puts their answer sheet (answers down) on their paper in the front.  Then | |

| | |while the participants work at their new station, the teacher grades and | |
