✅ Investigation Method Checkpoint

Each team presents its final question, hypothesis, and data-collection method in a brief teacher conference using the pricing sheet and notebook as evidence. The teacher checks whether the method can produce traceable calculations and whether the team is ready to move into systematic data gathering. Students make any required revisions before approval; if time remains, pairs complete the required oral debrief about one ratio or percent strategy, one corrected mistake, and one teamwork move that kept them organized.
