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
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
Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, admires the modern structure of a high rise building in the Arts District and highlights the fact that there are many different ways to look at a mathematical problem. These methods may include: decomposition of the larger area into smaller rectangular areas and finding the larger area and then subtracting the areas of each rectangular array. He illustrates these methods by observing the windows on... CONTINUE READING
Estimation, quantity, and scale help us understand aspects of the world around us that we can’t always interact with directly – these tools help us understand large objects and numbers, and ways to represent them. We discuss the questions students at the St. Philip’s School and Community Center posed within this math theme to show just how intuitive this can be! This material is based upon work supported by the National Science Foundation under Grant DRL 2115393. Any opinions, findings, an... CONTINUE READING
