Dr. Rebecca Klemm Just Returned From Speaking at ISTE 2017

ISTE 2017 Poster SessionDr. Klemm, PhD, was invited to return to ISTE this year and to host a poster session exploring the idea of “Building NumberOpolis,” a town where all of Team Ten and the STEM Squad live, in homes customized to match each number’s personality. During the session, the booth was constantly full of a steady stream of curious conference attendees. One teacher commented, “Your booth was my fav. Love meeting people as passionate (or more) about numbers as me” (LD)! Dr. Klemm and NumbersAlive! were excited for the opportunity to spread the idea to educators nationwide that math can be fun, engaging, explorative, and integrated with any other subject imaginable.

Greece’s Rio-Antirrio Bridge

rio-antirrio bridge

The proof of arithmetic is everywhere you look.  On my recent trip to Greece, this was proven profoundly through the artifacts and architecture in and around this gorgeous city. One of the most spectacular examples of the vivid world of arithmetic lives within the Rio-Antirrio Bridge, one of the world’s longest suspension bridges.

The support cables create a sail-like appearance!

The bridge is supported by four pylons; these are the large posts that reach from the bottom of the Gulf of Corinth to a whopping max of 524 feet (160m) above sea-level. Reaching further into the architecture arithmetic, each pylon splits into four beams creating an open area square pyramid atop the initial hexagonal structure of the lower pylon. This design was chosen in order to limit the amount of wind contact on each part of the bridge. The base of each pylon sits on the bottom of the gulf and is able to move laterally to absorb potential seismic activity.

Despite the use of the pylons, no part of the actual bridge is supported by the pylons, but by a multitude of suspension cables. Eight sets of 23 suspension cables connect from the top of each pylon to each of the five spans. The spans are all connected by six different expansion joints. When added together, they total an impressive 9,449 feet (2880m) in length across a 2- mile (3 km) expanse of water.

With so many visual measurements, basic arithmetic is easy to accomplish. How many support cables are there? How many pylons can you see? What shape is at the top of each pylon? These are just a few questions you could ask to stir immersive and critical learning centered around travel and bridges.

Mississippi State University Presentation

June 19-20, 2016

Later this month, The Numbers Lady will be presenting through the Math Science Partnership program at Mississippi State University! She will be providing instruction on how to teach math in a way that promotes numeric literacy to middle school teachers as part of MSU’s IMPACT2 initiative to “deepen the content knowledge, pedagogical skills, and technology-integration skills of 4th – 6th grade math teachers from across Mississippi.”

INPEX Invention Show

June 7-9, 2016

This weekend, June 7-9, The Numbers Lady will be traveling to Pittsburgh, PA for INPEX’s Invention Show where she will exhibit the newly patented Number Linx/Puzzling Polygons. NumbersAlive! will have a booth at the show that will also display a clock floor puzzle and a decagon floor puzzle. The clock puzzle has 25 pieces, and when assembled a dodecagon-shaped clock is created that shows not only the hours but also the minutes in five minute increments. Hopefully we’ll meet some new friends who are excited to see NumbersAlive! continue to create and grow! Feel free to stop in and say hello at Booth 514!
