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 Do You Measure Pitch and How is it Helpful?

  • September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, notices the two systems of ramps that lead into the Wyly Theater Center at the AT&T Performing Arts Center. He takes some quick measurements to figure out the slope, gradient or pitch of each of the two ramps, and then discusses how mathematics keeps us safe.

What’s the Really Big Number here?

  • September 9

Elementary students in the after school club came up with ideas for a math walk around their campus. In this math walk stop, they explore the hallway leading to the school cafeteria through their math lens. Research conducted during this semester-long afterschool club led to this research paper: Wang, M., Walkington, C., & Dhingra, K. (2021).

Similar Triangles or Not?

  • September 9

What are similar triangles and how can we tell if triangles are similar or if they are not? Students and faculty from CityLab High School, Dallas ISD join us on a beautiful day at Fair Park, an architectural treasure trove in the city of Dallas to explore this question using the sights of the Esplanade.

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

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

Why is the Ceiling Made of Triangles?

  • September 9

Why do we see so many triangles in buildings? Why is it one of the strongest shapes? We invite all interested groups to reach out and find more information on creating content of their own math walk or STEM walking tour with us at https://talkstem.org/create-your-own-walkstem.... CONTINUE READING

How Did the Artist Create this Illusion?

  • September 9

Room in the Mind by Patrick Hughes is a work of art depicting library shelves that seem to move and shift as you walk around the piece. This makes uses of motion parallax and forced perspectives to create the illusion of depth - something we discuss here. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

What are the building blocks of the mosaic?

  • September 9

What is the basic unit used to create this mosaic? We use math to figure it out! We invite all interested groups to reach out and find more information on creating content of their own math walk or STEM walking tour with us at https://talkstem.org/create-your-own-walkstem.... CONTINUE READING
