Use the Floats and Anchors context as well as physical and digital materials to help students understand integer addition and subtraction.
Construct It! Introducing Integers with Floats and Anchors
Christy Pettis and Aran Glancy
Encouraging Students to LOVE MATH with One-Straight-Cut Letters
Yi-Yin (Winnie) Ko, Connor A. Goodwin, Lauren Ream, and Grace Rebber
One-straight-cut activities engage middle-school students in learning about symmetry and geometric transformations.
Varying the Intensity of Scaffolding for English Learners
Haiwen Chu, Jill Neumayer DePiper, and Leslie Hamburger
Vary the intensity of pedagogical scaffolding along three dimensions—grouping, structure, and language—with the same rigorous prompt.
Two Technology Frameworks: Their Use in Lesson Design
Elizabeth B. Harkey, Angela T. Barlow, and Victoria Groves-Scott
The authors used two technology frameworks to design three seventh-grade mathematics lessons, focusing on opportunities to address collaboration, authenticity, or personalization.
Discuss It! Collaborating on the Tortoise and Hare Task
K. Ann Renninger, Maria Consuelo De Dios, Annie Fetter, Maeve R. Hogan, Moe Htet Kyaw, Ana G. Michels, Marina Nakayama, Richard Tchen, Stephen A. Weimar, Helena Werneck de Souza Dias, and Feven Yared
The authors share an online collaborative problem-solving activity that integrates support for students’ developing conceptual understanding, focused engagement, and positive feelings of agency and identity.
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.
STEM and Social Consciousness
Krystal Jones Carter
A well-crafted classroom engineering challenge can effectively answer compelling questions about social and global responsibility.
Advancing Agency Through Conjecturing
Support students in conjecturing in ways that can promote their agency in the learning process.
Building on Student Assets Through Number Talks
Jodie A. Bailey
This author used Number Talks as an asset-based approach to build on students’ prior knowledge and make connections across strategies in a Grade 7 mathematics class to address unfinished learning that occurred as a result of the COVID-19 pandemic.
Using Mathematics to Design a Droid
George J. Roy, Matthew Cunningham, and Kenneth Rafanan
Teachers have the opportunity to make mathematics relevant. We leveraged the popularity of Star Wars to engage students in exploring and connecting two dimensions and three dimensions to careers in toy design.
