Confirmation Bias for Grades 3–5
This guide helps US upper elementary 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. Students can compare two sources and explain a reason for trusting one over another. Pair independent reading with structured group debriefs. Use it to plan a single lesson or a short unit arc in 3–5 — then explore how Split a Cookie (SaC) modules reduce prep time for teachers and substitutes.
