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
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.
Crack the Code
Karen Zwanch and Bridget Broome
This game teaches algebraic generalizations through differentiated play in pairs, small groups, or as a whole class and uses manipulatives to bridge numerical and algebraic thinking.
Looking for Math in All the Right Places!
This article describes how fortuitous mathematical moments should be noticed, encouraged, embraced, and capitalized upon.
Five Core Routines for Teaching Mathematics Outside
Katherine Baker, Scott A. Morrison, and Mirella F. Cisneros Perez
Integrating mathematics and nature offers students benefits for physical and mental health and enriches their learning.
Smiles: A Strengths-Based On-Ramp Mathematics Task
Dorothy Y. White
Use this activity to support students in working together, recognizing one another’s contributions, and leveraging their mathematical strengths to solve challenging problems.
Teaching Is a Journey: Partner Quizzes to Support Learning
This department provides a space for current and past PK–12 teachers of mathematics to connect with other teachers of mathematics through their stories that lend personal and professional support.
Student Engagement with the “Into Math Graph" Tool
Amanda K. Riske, Catherine E. Cullicott, Amanda Mohammad Mirzaei, Amanda Jansen, and James Middleton
We introduce the Into Math Graph tool, which students use to graph how “into" mathematics they are over time. Using this tool can help teachers foster conversations with students and design experiences that focus on engagement from the student’s perspective.
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.
A series of tasks encourage students to reflect on the reasonableness of their number sense and use benchmarks to refine their estimations.
