Challenge: Students debate to “win” and get upset. Tip: Make “evidence + repeat-back + common ground” required. Praise bridge-building and respectful listening.
Challenge: Students give opinions without evidence. Tip: Use evidence packs for younger children and require them to physically point to the card/fact they’re using.
Challenge: Some students dominate; others stay silent. Tip: Use timed turns, role rotation, and give quieter students the Bridge Builder role first (then switch).
Challenge: Evidence is misunderstood or too difficult. Tip: Keep evidence age-appropriate (pictures, short stories, class data). For advanced groups, teacher curates 1–2 child-friendly sources.
