Nicole R. Rigelman and Introduction by: Sam Rhodes
Charles F. Marion
The simplest of prekindergarten equations, 1 + 2 = 3, is the basis for an investigation involving much of high school mathematics, including triangular numbers, arithmetic sequences, and algebraic proofs.
Michelle T. Chamberlin and Robert A. Powers
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.
Victoria R. Jacobs, Susan B. Empson, Joan M. Case, Amy Dunning, Naomi A. Jessup, Gladys Krause, and D’Anna Pynes
The authors introduce an activity involving “follow-up equations” to connect with ideas children have already expressed during fraction problem solving.
Lauren R. Holden, Yi-Yin (Winnie) Ko, Devon W. Maxwell, Connor A. Goodwin, Cheng-Hsien Lee, Jennifer E. Runge, and Elizabeth B. Beeman
One-Straight-Cut-Heart activities can help teachers support students’ engagement with geometry and can deepen students’ geometric reasoning.
Marina Basu, Karen Koellner, Jennifer K. Jacobs, and Nanette Seago
This set of tasks progressively engages students in geometric proportional reasoning.
Robert Powers, Michelle Chamberlin, and William Dutmer
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.
Carrie Plank and Sarah Roller Dyess
Use these three strategies to support student perseverance and discourse about context.
Alisan Boes, Duane C. Boes, and Nichola Hillis
We explore the statistical likelihood of one, or more, siblings in a family of nine surviving to 100 years of age.
