Get the Math: Take the Challenge
Watch videos of young professionals in the fashion, videogame, and music industries as they introduce four teenagers to their emerging businesses, studios — and algebra challenges.
Fashion designer Chloe, who won season two of “Project Runway,” asks the four teens to use proportional reasoning — and a sense of style — to take apart a poly charmeuse top, re-envisioning the sample shirt in a way that trims $5 off the cost of its fabrics.
A developer of online games for Facebook and other websites, Julia tasks the teens with programming a version of “Asteroids” by drawing on coordinate graphing and linear equations.
DobleFlo hip-hop artists Manny Dominguez and Luis Lopez challenge the foursome to adjust the tempo of an instrumental sample to synch it up to a drum track, which requires calculating beats per minute.
Compiled and edited in the style of reality-TV game shows, these clips stop to let you try the math using the interactive tools provided; then resume to show how the four adolescents creatively applied algebra in these contemporary fields of art and design.
For this program of WNET’s THIRTEEN, DobleFlo recorded the original rap “Get the Math.” Download a free mp3 of the song here:

458: HAPPY THANKSGIVING
Grandmother Brown is going to host a huge family gathering on Thanksgiving Day. She has eight grandchildren, and this year she has decided that they will all help with serving or cleaning up. The kitchen is small, so she must select four of the children to wash dishes after the meal. The others will help with serving during the meal.
The selection is not an easy matter, however, for there are jealousies and attachments among the children that prevent a free choice of four dishwashers. Can you help Grandmother select a dishwashing crew of four while satisfying all these whims?
- Travis will work with anybody.
- Michael won’t wash dishes unless Vinolia helps too.
- Vinolia won’t work with Jen.
- Nicholas won’t work without Funmi.
- Jen will work with anybody.
- Clark won’t wash dishes with Nicholas unless Stephen helps too, and won’t work with Vinolia unless Nicholas also helps.
- Stephen won’t work with both Michael and Vinolia, and won’t wash dishes with either Travis or Jen.
- Funmi won’t help unless either Michael or Clark wash dishes, and won’t work with Vinolia unless Stephen works too, and won’t work with both Travis and Jen.
Please state the names of the four grandchildren who will be washing the dishes, and give a full explanation of how you made your selection.
2780: THANKSGIVING TRAVEL
Zach is planning to drive to his parents’ house in Philadelphia for Thanksgiving. He lives in Pittsburgh so he can either take Route 30, which is a scenic drive, or take the Pennsylvania Turnpike. He’s trying to decide between the two routes. Here are the details that he’s considering:
– distance is 305 miles each way
– toll road charge is $9.00 each way
– 1/61 of the trip is city driving and 60/61 is highway driving
– distance is 372 miles each way
– no tolls
– 1/3 of the trip is city driving and 2/3 is highway driving
Gas costs on the average $1.60 per gallon. Zach’s car gets 25 miles per gallon in the city and 30 miles per gallon on the highway. (Route 30 involves more city driving because he’d be driving through a lot of small towns.)
Explain which plan is the most economical (not considering the time involved or the wear and tear on his car).

Use the digits in the year 2009 and the operations +, – ,x, divide, and ^ (raised to a power), sqrt (square root) and ! (factorial), along with grouping symbols, to write expressions for the counting numbers 1-100. You can use decimal points and double-digit numbers.
1. All four digits must be used in the expression.
2. Only the digits 2, 0, 0, 9 may be used.
3. Multi-digit numbers such as 20, 209, oor .02 MAY be used.
4. Submit answer without using equal signs.
Example for number 11:
Correct format: (2 + 0)-0+9
Incorrect format: 2+0=2-0=2+9=11

I wonder…….. Current Problem of the Week 10/20/08
Jerson is selling fruit at the Farmers’ Market. To attract customers to his booth, he has made up a contest! He has these photos of combinations of fruit on display. His contest is to find out how much each fruit weighs.
Note: Assume that both of the melons weigh the same, both of the pineapples weigh the same, and both of the limes weigh the same.
Melanie looks at his photos and tells him, “I know how much one melon weighs.”
How might Melanie have figured out how much one melon weighs? How much does each type of fruit weigh?
There will be a math test next week. Ratio, proportion and rate are the topics. Study PowerPoint lessons 3,4,5.
