Before the excavation began, Emek and Luna organized supplies for 7 digging teams while Dr. Dino checked the equipment list. Each team needed 9 fossil tags and 9 hand brushes packed together. They used multiplication to confirm they needed 63 tags and 63 brushes altogether. After preparing every identical supply set and checking that each team received one, the excavation started on time with everyone fully prepared.
