✅ Rounding Methodology Checkpoint

Students exchange notebooks with a partner to review rounding accuracy and data completeness using a provided checklist. Partners verify correct identification of place value digits and whether numbers round up or down (0–4 down, 5–9 up). Students correct at least one identified error and highlight any discrepancies discovered during peer review. The teacher conducts quick spot-checks to confirm consistent methodology before moving to analysis in the next phase.
