How many angles can you find using the angle-a-tron?

• September 9

High school members of the Women in STEM club in Greenhill School stop at the playground on their math walk to share some math with the second graders. There are angles all around us on our campus, including in the branches of the trees, and the walls of our buildings. How can we use our angle-a-tron tool to measure some of them? What can we learn about the different angles around us? You can freely print the shapefinder tool as well as the angle-a-tron tool onto an acetate using this pdf:... CONTINUE READING

How Do Cylinders Make Beautiful Shapes?

• September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, is struck by the cylinders obvious in the design of this modern building. The building is formed from two cylinders that intersect to form a beautiful parabola.

What are Fractals?

• September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, notices the beautiful, glossy leaves of the magnolia leaves that he walks by on this tour and call out the math pattern of the veins in the leaves. This fractal pattern, where the shape repeats itself but at a progressively smaller scale is common in nature and is a fascinating, relatively new field in mathematics.

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 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 Can Shapes Create Feelings?

• September 9

Architect I. M. Pei designed this visually striking building. Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, points out that the effect of the design is dependent in part on the use of two geometric shapes that are unexpectedly used together.

What is a Mathematical Fossil Hunt?

• September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, takes us on a mathematical fossil hunt as we observe a modern water feature at the Texas Sculpture Walk.

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 is the shape of the traffic bollard?

• September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, rapidly brainstorms a series of questions about the traffic bollards on an urban street. He illustrates for us that the math and STEM-related questions we can ask about everyday objects are almost endless and that it's a lot of fun to ask these questions in our everyday lives!...

Can Math Help Grass Grow?

• September 9

Dr. Glen Whitney, founder of the National Museum of Mathematics in New York and walkSTEM advisor, rapidly brainstorms a series of questions about the grasses he notices in the planters outside a building on a busy street. He illustrates for us that the math and STEM-related questions we can ask about everyday objects are almost endless and that it’s a lot of fun to ask these questions in our everyday lives!...
