Confirmation Bias for Grades K–2
This guide helps US primary classrooms teach confirmation bias with clear objectives and classroom-ready activities. Students learn why people accept convenient claims and how to stress-test their own assumptions. Use short texts, picture prompts, and guided discussion. Keep vocabulary concrete and revisit the same media literacy habits weekly. Use it to plan a single lesson or a short unit arc in K–2 — then explore how Split a Cookie (SaC) modules reduce prep time for teachers and substitutes.

Standards alignment note
Districts across the United States align Grades K–2 media literacy instruction to state ELA, social studies, and library standards. SaC resources support local adoption — they do not replace state-specific scope and sequence requirements. Review your state framework when mapping K–2 outcomes.
