Numbers Lady

Rebecca Klemm, PhD (Statistics) has spent 50 years teaching students from Pre-K to PhD and adults, including staff hired for her research and evaluation firm, Klemm Analysis Group, Inc. She created and produced a “bucket-list” musical about math during 2010. Parents and teachers asked that she expand the ideas presented in the musical to help demystify math, make math meaningful and increase mathematical thinking. In 2012 she adopted the persona, The Numbers Lady® and began writing books with rhyming text and inventing learning tools demonstrating where numbers are embedded in everything in life, worldwide: in art; science; architecture; sports; nature, culture; folklore; etc.

As interest grew, she expanded the offerings to individual and team STEM/STEAM creative and maker experiences: “Hello We’re NumbersAlive!” musical about math; “Building NumberOpolis!” the town where the numbers live and work; and a studio video series, “The Numbers Show.” During 2019 she experimented with incorporating students as members of the writing and producing team of a new global video series, “The Global Traveling Numbers Show.” The successful initial episode was created in Houston, TX and the second was scheduled for filming in Botswana in March 2020. Covid-19 postponed the filming until global travel and arrangements can be re- scheduled.

NumbersAlive! believes that no one is too young to start learning about the universality of numbers and math – and that their relevance should be engaging, interesting, and downright fun! Putting numbers into a real world contexts and looking at them through the lenses of art, history, science and culture propels math out of academic abstraction and into a vital part of everyday life. NumbersAlive! creates award- winning educational learning tools (toys, books, and more), out-of-school experiences and professional development. We use the arts and real-world adventures to encourage learners of all ages to observe and speak about numbers in their own environments. This establishes a solid knowledge foundation for STEM (science, technology, engineering, and mathematics) or STEAM (STEM plus arts) academic subjects. Team Ten®, led by Zero the Hero, accompanies The Numbers Lady and learners on innovative, interpersonal, and interactive global education quests. They discover numerical applications and develop concepts of the scientific method. The STEM Squad®, led by π investigates more complex numerical patterns and applications.

Presentations by the Numbers Lady

Meet Team Ten, World Numbers 0-9

The following slides present a visualization approach to mathematics compiled from the original projections created for the 2010 musical, “Cookin’ Up Numbers.” The concept of visualizing mathematical ideas were the fundamental impetus of parents and teachers to encourage Dr. Klemm to continue developing NumbersAlive! to demystify mathematics and encourage mathematical thinking.
