Dr. Klemm to speak at the July 12th STEAM 4.0 + MeWEE Conference

July 12, 2017

Rebecca Klemm, PhD is headed out to Northern Virginia to the STEAM 4.0 & Meaningful Watershed Experiences Professional Development Workshops presented by the Virginia Association of Science Teachers, Region IV. The conference will take place at the Charles Colgan Sr High in Manassas, VA.

She will speak twice:

9:05-10:05, Number Links with Team Ten for Elementary Teachers

12:05-1:05, Building NumberOpolis!s about Building NumberOpolis for MS and HS Teachers






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.

NumbersAlive! Recently Named One of the Top 100 Social Media Influencers in the K12 Market

On June 2, 2017, EdWeek Market Brief reported that NumbersAlive! was among the 100 top social media influencers of the US K12 market, due to the content of our tweets, the number of our Twitter followers, and our Klout score.

This is exciting news, as it values the educational contributions of NumbersAlive! right alongside those of much larger education organizations and corporations. Bigger is not necessarily better.


How the ranking was determined

Realizing that educators, leaders, and technologists are increasingly turning to Twitter for social and professional reasons, EdWeek Market Brief partnered with the Education Week Research Center to identify companies to evaluate and rank based on social media influence. The influence was calculated using two metrics: number of Twitter followers and scores from Klout.

Klout is “a social media-monitoring service that uses an algorithm to track accumulated influence across networks and assign a numerical value between 1 and 100 to show results over a 90-day period.” The top six organizations had Klout scores of 80-86; at 93 of 100, NumbersAlive!’s score was 44.

Ancient Grecian Urn

Grecian UrnJust imagine all the engaging math lessons this beautiful Grecian Urn can inspire!

Look at all the patterns on its surface. How many do you count? There are lots of geometric shapes making up the patterns. I see triangles, rhombi, and squares. I also see some funny shapes that have one curved side, like the people kneeling, and some shapes that have lots of sides and go on and on and on all around the urn in the part that looks like a maze. What names would you give these shapes?

Notice the cracks covering the urn’s surface. It is very old, and was buried underground for many years, probably thousands! The archaeologists, people who study human history, who found it had to put it back together, piece by piece, like a big 3D puzzle. Do you think it was tricky? I think the patterns might have given them a few clues!

I don’t think those patterns were easy to carve, though. Back when this urn was decorated, the design had to be carefully thought out, drawn, and measured, all by hand! The Ancient Greeks only had simple tools to help them, not powerful electric tools and computer programs like we have today. Do you think you could plan a design for an urn without any technology? Give it a try!

Where else do you see patterns in the world around you? Dishes are still decorated with patterns that go all the way around! And 9’s favorite sweater has a repeating pattern of black and white stripes, just like the stripes on this urn. What other patterns do you use or see every day?

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.
