GPS: Diving into Dolphin Data
Rebecca Robichaux-Davis, Cheng-Yao Lin, Jennifer M. Bay-Williams, and Aviva Hamavid
Visualizing the Arithmetic Mean
Michael Daiga and Shannon Driskell
The two provided activities are geared for students in middle school to facilitate and deepen their understanding of the arithmetic mean. Through these activities, students analyze visual representations and use a special type of statistical thinking called transnumerative thinking.
Partial Pies
Jennifer Marshall
A series of tasks encourage students to reflect on the reasonableness of their number sense and use benchmarks to refine their estimations.
When Students Use Technology Tools, What Are You Noticing?
Lara K. Dick, Allison W. McCulloch, and Jennifer N. Lovett
A framework to guide teacher noticing when students are working in technology-mediated learning environments.
GPS: From Folding to Dynamic Geometry Environments
S. Asli Özgün-Koca and Matt Enlow
In this month's Growing Problem Solvers, we focused on supporting students' understanding of congruence and similarity through rigid motions and transformations. Initial understandings of congruence and similarity begin in first grade as students work with shapes in different perspectives and orientations and reflect on similarities and differences.
Problems to Ponder
Steve Ingrassia and Molly Rawding
Problems to Ponder provides 28 varied, classroom-ready mathematics problems that span grades PK-12, arranged in order of grade band. Links to the problem answers are available in this department.
