How many sections are there?

  • September 9

A high school student at Hockaday School created a campus STEM walk for elementary students to enjoy. In this walk stop, she looks at the beautifully statue of Hypatia, an ancient Egyptian mathematician and astronomer who died 415 AD. Here she notices the circle surrounding the sections and asks us to do some math to figure out the number of sections within this circle.... CONTINUE READING

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

How Fast Can You Go?

  • September 9

Whether you’re at Fair Park or even driving around certain parts of Dallas, it’s hard to miss the towering site of the Texas Star Ferris Wheel! After all, it’s the largest Ferris wheel in the United States. As you’re watching it turn, there are lots of things you might wonder about, but if you’re like us, one of the first that comes to mind is: How fast is your gondola whisking through the air when you ride it? Join students and faculty from Greenhill School in exploring this question.... CONTINUE READING

What’s the Scale?

  • September 9

The giant mosaic North Texas Sunrise depicts many native texan flowers, all far larger than life. Using a standard 8.5" x 11" sheet paper as a measuring device, we calculate how much larger the mosaic flowers are than the real thing, determining the scale of the artwork.

What’s the farthest distance between 2 points on the map?

  • September 9

Does it ever seem like you parked at a store that is farthest away from the store you want? Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how to determine what the farthest points are within NorthPark Center.

What’s the biggest store?

  • September 9

Join Dr. Glen Whitney, Founder of the National Museum of Mathematics, as you discover how to best estimate which store is largest, given a map. This video was supported by NorthPark Center.

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

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. This video was supported by the City of Dallas Office of Cultural Affairs. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:...

How Can We Estimate the Amount of Water on Earth?

  • September 9

The terrazzo World Map in the main lobby provides a fairly accurate representation of the Earth’s surface. Using the lines separating its sections to divide it into quadrants, we can use fractions to estimate the portion of the whole covered by water. Combining these parts back together and comparing it to established numbers should give us and idea of how close we were able to get with our estimation! This video was supported by the City of Dallas Office of Cultural Affairs. Supplementary Act... CONTINUE READING

What Can You Measure in Bamboo Plants?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, wonders what we can measure in the bamboo plants located at the entry to the Nasher Sculpture Center. Suggestions include length of nodes, distance between leaves, circumference of stalks, and more. Dr. Whitney then explores the possibility of a mathematical relationship between some of these measurements and age of the bamboo. How would we figure out if there was a relationship and also what type o... CONTINUE READING
