What is the Really Big Number Here?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, has fun with a really big number by estimating the number of stones that were used to build the sidewalk on Flora street. Using number arrays, estimation, and collaborative groupwork, Dr Whitney and friends come up with their estimate and then visualize how tall of a tower these stones would be if they were to be stacked up vertically. Can you guess? Supplementary Activity Guides for this video to e... CONTINUE READING

What is the angle at the very top of the Ad Astra sculpture?

  • September 9

Join Dr. Glen Whitney, founder of the National Museum of Mathematics on a math walk. With the help of friends, he attempts to estimate the angle at the top of this very tall angle at the top of the Ad Astra sculpture. This video was supported by NorthPark Center.

How tall is the Ad Astra sculpture?

  • September 9

Join Dr. Glen Whitney, founder of the National Museum of Mathematics on a math walk. He uses the power of similar triangles to calculate the height of a giant sculpture inside the NorthPark Center. How can we estimate the height of the sculpture without getting a ladder? This video was supported by NorthPark Center.

How does geometry relate to the Campanile Windows?

  • September 9

The stained glass of Campanile Window, by Octavio Medellin, contains irregular quadrilaterals – four-sided shapes with sides of different lengths – interspersed with lines and triangles in varying angles. In combination, all these lines create a sort of linear perspective, mimicking the way images shrink and converge as they recede from a viewer. Despite being made of flat, static glass, those design elements give the piece a clever way to convey a sense of energy and motion that matches wel... CONTINUE READING

How Large is the Art?

  • September 9

Martin Donlin’s multi-panel work Blueprint of Flight spans a large portion of the pedestrian walkway wall. By measuring the size of single one of these panel, and multiplying by the number of panels in the work, we can begin to calculate the square footage of the piece as a whole.

How Much Gold is There?

  • September 9

Perhaps the most eye-catching feature of Dallas Fair Park is the gold-leaf wrapped Tower Building. Yes, that is real gold! Because of the allure and attraction of gold, we definitely want to ask, “How much is all of that gold on the Tower Building worth?” Before we go through the calculations, stop and take a moment to guess. Is it 1,000 dollars worth of gold? $10,000? A million dollars? Let’s figure it out. Supplementary Activity Guides for this video to extend student learning for K-12 g... CONTINUE READING

What’s the biggest store?
