The theme this issue is access, and most of it runs through technology. Edwards, Yang, and Zeng hand English-speaking students a board game, Where are the Cherries?, and ask them to learn the rules from an instructional video in Chinese; by the end the students have sharper problem-solving and a clearer sense of what ELL classmates manage every day. Bouchat and Barnard put Desmos to work modeling real data so that polynomial end-behavior has a reason to exist before the rules arrive.

Joswick, Conner, and McMillan take Visual Dot Card Number Talks, a routine for building number fluency and hearing how other students think, and rebuild it in Nearpod and Desmos for classrooms that might be virtual, hybrid, or in person. Closing the issue, Oxman gives a proof without words: an elegant relationship among the cevians of an acute triangle and the angles they form, no technology required.
