Mission 2: Activity B - Find a Location for the Yummy's Franchise
Approximate time needed to complete: 10-15 minutes
In the second activity, Dr. Wick is trying to decide where to build his flagship Yummy's! restaurant. To foil his plans, the Agent is asked by the AVU to calculate how many children (age 1-9) live in each of five cities sing a number of different graphs, charts, and tables. After entering their calculations, the Agent must select the city with the fewest number of children (age 1-9) living in it.
The number of children in each town are:
5.4% + 6.2% = 11.6%
0.116 x 32,003 = 3,712 children age 1-9
3.5% + 3.7% = 7.2%
0.072 x 24,561 = 1,768 children age 1-9
4.7% + 7.6% = 12.3%
0.123 x 93,343 = 11,481 children age 1-9
1.9% + 2.9% = 4.8%
0.048 x 807,322 = 38,751 children age 1-9
5.0% + 5.2% = 10.2%
0.102 x 23,721 = 2,420 children age 1-9
The town of Spurious, with a total of 1,768 children age 1-9, has the fewest children in it.
Special Problem Notes:
Students should click on a town to see the population breakdown.
There are 5 views of the data: a table, a histogram, a pie chart, a line graph, and a box-and-whisker plot.
Students must enter the child population in the box at the bottom of the city window.
Child populations should be rounded to the nearest whole child.
When a correct child population is entered, the entry box will In addition, a sign with the child population will be plastered over the regular population sign on the main screen. In addition, a sign with the child population will be plastered over the regular population sign on the main screen.
When students have entered correct child populations 4 out of the 5 cities, including Spurious, the answer submission drop-down menu will appear.
If students notice that the percentages in the table and pie chart views do not add up to exactly 100 percent, it is due to the cumulative effect of rounding.
To use tools, simply click them from the bar on the left side of the screen. To close tools, use the "Ok" button or the close "X" in the upper left corner of the tool.
The 3 steps on the To-Do list are:
Step 1: Click towns to see population data and figure out how many children (1-9) live there.
Step 2: Enter the number of children (1-9 years old) that live in the towns.
Step 3: Choose the town that has the least children in it.
"Wick's given us a golden opportunity to sabotage his plans. Have him build his restaurant in the town that has the least children in it. Let's say everyone 9 years old and younger counts as a child. Good luck!"
Students can type letters and numbers into their notepad. Their notes travel with them throughout the whole mission.
Students can use the calculator by typing number on the keyboard or clicking with their mouse.
Clicking on a city reveals tabs with 5 different views of the same population data, some of which are more applicable than others. Of the five, only the table view and pie chart have specific values for each range. This the table view for all 5 cities.

AVAILABLE FIELD AGENTS
Pascal the Koala
Pascal shows and discusses the different uses of all five types of data representation. The vocabulary terms population, line graphs, box-and-whisker plot, and pie chart are all used.
Garbanzo al Dente
Garbanzo suggests using estimation to get rid of the towns with the largest populations, noting that the town of 4.8% of 807,332 (like in Counterfeit) will still be more than 7.2% of 24,561 (like in Spurious). The vocabulary term population is used.
Kotori sketches the table view of the population data, then crosses out the inappropriate data (where 10-14 up to 85+ would be), leaving only the useful population data.
Coach reminds not to compare percentages, but instead total number of children. He also hints that there is a need to convert from a percentage to a decimal in this problem. The vocabulary terms percentage and decimal are used.
Mathbot gives the formula C = %/100 x P to calculate children in a city, explaining what each symbol means in a different voice. The vocabulary term population is used.
After 15 seconds: Deep Thought notes that to find an answer, both percentages and total population of the town will be needed. The vocabulary terms percentage and population are used.
After 15 more seconds: Deep Thought reminds that the 1-5 and 5-9 year-old groups will need to be added together to find the total percentage of children in a town. The vocabulary word percentage is used.
After 45 more seconds: Deep Thought uses an example town to show how to figure out the number of children in a town. Using the pie chart, Deep Thought adds the percentages for the 1-5 and 5-9 categories together. He then divides that total by 100 to turn the percent into a decimal. Finally, Deep Thought multiplies the decimal by the total population to find the number of children in the example town. The vocabulary words population, pie chart, percentage, and decimal are used.
