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.

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!

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

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).
