Students will launch the snack-splitting investigation by modeling a fair-share problem in teams of 4, recording first ideas and revisions on a snack division poster, using visual models and equations to test fraction decisions, and pausing for thumb-rating check-ins that set expectations for later investigation rounds.

Students will present and defend a fair-share snack solution using visual models, equations, and revision evidence, then complete a real-time team challenge and class showcase for the Fraction Fixers Fair.

Students will investigate a snack-splitting mystery, develop a fair-share question and hypothesis, draft a fraction strategy with models and equations, build an evidence checklist for revision rounds, exchange peer feedback, and revise their planning on the snack division poster before solving.
