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. Supplementary Activity Guides for this video to extend student learning for K-12 grade levels are freely available here:... CONTINUE READING

How do we make the Swing go high?

  • 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 swing on their playground through their STEM lens. Research conducted during this semester-long afterschool club led to this research paper: Wang, M., Walkington, C., & Dhingra, K. (2021).

What Kinds of Angles Are There?

  • September 9

Angles can be found all around us, but what types of angles are there? We find various angles on UT Southwestern’s Medical Center to discuss! Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus. You can freely print the angle-a-tron tool onto an acetate using this pdf: https://drive.google.com/file/d/1JPfBIatPfkZzi... CONTINUE READING

How Can We Calculate Pi?

  • September 9

Pi is a number describing the ratios various parts and measurements of circles have with each other, meaning we can calculate it from any measurable circle – including this sculpture, Sun Disc Triptych by Jesús Moroles. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

How Do We Measure Slope?

  • September 9

Slope is a way of describing the way that a line or plane – like a sidewalk – changes over a distance. Using these principles, we describe the way the grounds around us were built. Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

How Many Circles Make Up this Pattern?

  • September 9

There’s a pattern of overlapping circles in the ground pavement around the medical center – but is there any way to estimate how many circles there are? We investigate a few different methods of figuring it out! Join talkSTEM and UT Southwestern faculty and grad students as they explore the STEM concepts on their campus.... CONTINUE READING

How Big is Your Imagination?

  • September 9

The castle-shaped shelves in the Dallas Public Library picture book area is a fun way to incorporate imaginative architecture into a space. Designing these sorts of shelves requires quite a bit of math and planning – something we try to tease apart by taking measurements of its dimensions.... CONTINUE READING

What Shapes Can You Find?

  • September 9

The castle shelves in the Dallas Public Library are made up of a number of different basic shapes. Using our walkSTEM guide, we see just how many we can find! You can download and print your own shapefinder onto an acetate using this pdf: https://drive.google.com/file/d/1vBKbHnWZug5uBlM61LXAAEgU9dNaUwdY/view?usp=sharing... CONTINUE READING
