Thursday 1:30-2:30 - (169 BMK) GeoGebra Does THAT? Doing Statistics and Data Analysis in GeoGebra 10–12 Session

GeoGebra—widely used in algebra and geometry classes—has a robust set of statistics tools. In this session, you will learn how GeoGebra can be used to develop quantitative literacy in Statistics or AP Statistics through doing exploratory data analysis, creating dynamic data and regression displays, and conducting inference procedures and simulations.

Thursday 3:15-4:30 - (249 LOVE) Problem Solving + Assessment + Technology (GeoGebra and GoFormative) to Build Mathematical Knowledge 10–12 Workshop

Learn to blend problem solving and assessment using GeoGebra and GoFormative. We will solve, generalize and assess rich, open-ended, and powerful geometric and algebraic problems involving functions, polygons, parallels, and congruence and similarity. Presenters will share premade files. Bring your own device to fully engage and collaborate. Roberto Soto California State University, Fullerton Armando Martinez-Cruz California State University, Fullerton San Diego Convention Center, 24 ABC

Thursday 3:15-4:30 - (253 BMK) Transforming HS Geometry with GeoGebra: Featuring Activities from Illustrative Mathematics Geometry 8–10 Workshop

New standards have given high school geometry a fresh start. Dynamic geometry software allows activities with more opportunities for exploration and greater accessibility than traditional exercises. In this workshop, we will explore brand-new Illustrative Mathematics high school geometry activities using GeoGebra. Bring a laptop or tablet to join the fun.

Thursday 3:30-5:00 - (Networking Lounge: Math Circles) Award Winning Lessons for your Circle or Classroom

Congratulations to the 2018 Rosenthal Prize winners!Congratulations to Elizabeth Masslich, winner of the 2018 Rosenthal Prize for Innovation and Inspiration in Math Teaching for her lesson “Geometry Project: DARTBOARD.”  In Elizabeth’s lesson, students learn geometric probability using shapes on a dartboard.  Elizabeth is a teacher in the Milwaukee, Wisconsin metro area, and was awarded a $25,000 cash prize. Additional congratulations to the 2018 first runner-up, Hector Rosario of the Atlanta, Georgia metro area, for his lesson “Squareland: Into How Many Squares Can You Cut a Square?”  In Hector’s lesson, students generate and analyze patterns by cutting squares into smaller squares while making conjectures and trying to prove their claims.  Hector was awarded a $5,000 cash prize. The Museum also wishes to congratulate the 2018 runners-up, Dwaynea Golden of Hinesville, GA, and Kristen Rudd of Bergen County, NJ, who each received a $1,000 cash prize.

Friday 8:00-9:00 - (294 ASSESS) Is This Vending Machine FUNCTIONing Correctly? 6–8 Session

Understanding what a function is and isn’t is foundational to the concept of function. In this session, you will engage with a GeoGebra applet that develops an initial understanding and definition of function. Participants will view and discuss eighth-grade students’ work with the applet. Bring a laptop or tablet to engage with the applet! Lara Dick Bucknell University, Lewisburg, Pennsylvania Jennifer Lovett Middle Tennessee State University, Murfreesboro Allison McCulloch Middle Tennessee State University, Murfreesboro Hilton Bayfront, Indigo CG

Friday 9:30-10:30 - (358 LOVE) The Beauty of Harmonic Divisions of Golden Rectangle Designs 6–8 Session

The Golden Rectangle has been employed by artists from the Renaissance to Modern Times to convey depth and proportion. Participants will construct Golden Rectangles using GeoGebra. Diagonal lines drawn from vertices on rectangular grids will form beautiful symmetric designs in color and suitable for spectacular electronic bulletin board displays. Stephanie Cooperman Retired, Chester, New Jersey Neil Cooperman Millburn School District, New Jersey Hilton Bayfront, Cobalt 501

Friday 9:454-11:00 - (372 ASSESS) Problem Solving to Elicit Student Thinking 8–10 Workshop

Learn to solve problems, ask meaningful questions, assess student thinking, and adapt instruction. We demonstrate various techniques to blend problem solving and assessment of student thinking. We discuss polynomials, proportionality, and congruence and similarity, while using three tools: GeoGebra, Desmos and GoFormative. Bring your own device.
