Excited to facilitate "Integrating Technology in a 6-12 Thinking Classroom" with @peterliljedahl.bsky.social at #NCTMDEN26. Experience how tech can serve as an exploratory & coding tool, & leave w/tasks where tech can help foster fluency, enhance discovery, and provide hints and extensions! #edusky
