Broken Ceiling Lights: Circular Area Without the Radius
Nicholas J. Gilbertson
A customer walks in to a lighting store with a broken ceiling light, and the solution to finding a replacement glass illuminates an alternative approach to finding the circumference and area of a circle without knowing the circle’s center, radius, or diameter.
Adapt It! Adapting Stories and Technology for Engagement in Geometry
Karen L. Terrell, Dennis J. DeBay, and Valerie J. Spencer
A task to develop and provide access to mathematics for all.
GPS: Building Popcorn Boxes
Robert A. Powers and Michelle T. Chamberlin
Growing Problem Solvers provides four original, related, classroom-ready mathematical tasks, one for each grade band. Together, these tasks illustrate the trajectory of learners’ growth as problem solvers across their years of school mathematics.
The Do Nothing Machine
Keith Dreiling
The Trammel of Archimedes traces an ellipse as the machine’s lever is rotated. Specific measurements of the machine are used to compare the machine’s actions on GeoGebra with the graph of the ellipse and an ellipse formed by the string method.
The Mathematics of Sewing
Hanan Alyami
GPS: Triangle Explorations and Constructions Using Robots
Hyejin Park, Tuğba Boz, Amanda Sawyer, and James C. Willingham
Growing Problem Solvers provides four original, related, classroom-ready mathematical tasks, one for each grade band. Together, these tasks illustrate the trajectory of learners’ growth as problem solvers across their years of school mathematics.
See, Think, and Wonder Geoboard Art
Enrique Ortiz
Two original images were inspired by the use of an art studio app for digital drawings. This artistic process could be used to help created other original art and during See-Think-Wonder routines emphasizing meaningful observations and questioning skills.
Turning Trucks Into a Meaningful Geometry Exploration
Kate Roscioli and Jennifer Suh
Learn how to engage students in geometry concepts through a real-world task that leverages GeoGebra to provide students with generalization and authorship opportunities.
Teaching Angle as Turn Using a Code.org Lesson
Stacy K. Boote and Terrie M. Galanti
Elementary school students use physical manipulatives (e.g., pattern blocks) to make sense of the geometry and measurement ideas in a Code.org block-based programming lesson.
