One-straight-cut activities engage middle-school students in learning about symmetry and geometric transformations.
Encouraging Students to LOVE MATH with One-Straight-Cut Letters
Yi-Yin (Winnie) Ko, Connor A. Goodwin, Lauren Ream, and Grace Rebber
Let’s Give Them Something to Talk About
Nicola M. Hodkowski and Carolyn Carhart-Quezada
Different types of open tasks can be used as a tool to promote rigorous student mathematical discourse and considerations for facilitation.
Filling Vases and Making Tanks
Two classic hands-on tasks address conceptual understanding of functions. The tasks center student discourse and rough draft mathematics as students grapple with the relationship between input and output.
Making Sense of Algebraic Expressions in Context
Isabel White, Michael Foster, and Joanne Lobato
Explore three challenges that students faced and how they made progress.
Building Coherence and Progression on Sound Frameworks
Travis Lemon and Scott Hendrickson
A robust framework can support teachers and their students’ learning.
Dilemmas and Design Principles in Planning for Justice-Oriented Community-Based Mathematical Modeling Lessons
Jennifer M. Suh, Holly Tate, Maryanne Rossbach, Samara Green, Kathy Matson, Julia Aguirre, Padhu Seshaiyer, and Sam Steen
This article details the development of design principles to support teachers in planning for a Community-Based Mathematical Modeling task with a focus on social justice in the elementary grades. By reflecting on the dilemmas we encountered in the design and enactment of the tasks, we developed five design principles that allowed us to address issues of social justice as well as attend to powerful mathematical ideas to bring awareness and take action around a local problem. Through our article, we hope to share with mathematics teacher educators design principles to help plan for tasks with pre- and in-service teachers that prioritize connecting mathematics to social issues and empower both teachers and students to take action to make a positive impact in the community.
Technology and Median Income Data: Opening Doors
Gail Burrill, Joan Funderburk, Becky Byer, and Rachael Gorsuch
Classroom stories show how using technology to investigate the wage gap provided opportunities to develop students’ identities and agency and enabled a classroom culture of sharing and risk-taking.
Enacting Co-Craft Questions Using Flexible Teaching Platforms
T. Royce Olarte and Sarah A. Roberts
Teachers can implement a mathematics language routine within in-person/hybrid and remote instructional contexts.
Exploring Grades 3–5 Mathematics Activities Found Online
Lara K. Dick, Amanda G. Sawyer, Margaret MacNeille, Emily Shapiro, and Tabitha A. Wismer
We investigate resources on TeachersPayTeachers and discuss how what is available affects our teaching practices.
