Use 4 groups with one coordinator per group. 00:00–00:10: welcome and explain the activity. 00:10–00:20: distribute 24 clay blocks to each group. 00:20–01:05: run the main activity. 01:05–01:20: collect feedback and reusable equipment. 01:20–01:30: clean the east studio and check the inventory.

Count the 96 clay blocks before visitors arrive. Confirm a clear entrance and an accessible work area at the east studio, then give each of the 4 group leads the same timing sheet.

Supplies: 96 × $3.30 = $316.80. Reserve: $316.80 × 0.10 = $31.68. Planned total: $348.48. This is a planning calculation using the supplied prices.

Remove 24 units, leaving 72. Supplies become $237.60; a 10% reserve adds $23.76, for a total of $261.36.

Join Ceramic Open Studio this Thursday at the east studio. Meet neighbors, learn together, and take part at your own pace. We will share the available clay blocks across small groups. Supplies are limited, so please check with the welcome desk when you arrive.

Ceramic Open Studio Thursday · east studio Welcome! Ask the desk about available clay blocks and today’s small-group activities.

```python import csv def read_inventory(path): rows = [] with open(path, newline="", encoding="utf-8") as handle: reader = csv.DictReader(handle) if reader.fieldnames != ["item", "quantity"]: raise ValueError("Expected item,quantity columns") for line, row in enumerate(reader, 2): name = row["item"].strip() quantity = row["quantity"].strip() if not name or not quantity.isascii() or not quantity.isdecimal(): raise ValueError(f"Invalid inventory row {line}") rows.append((name, int(quantity))) return rows # Example row: clay blocks,96 ```

The row `clay blocks,96` should pass. The row `clay blocks,-1` should raise a ValueError because a negative quantity is outside the stated inventory contract. An empty item should also fail.

Handover — Ceramic Open Studio Location: east studio; day: Thursday. Inventory: 96 clay blocks, allocated as 4 groups × 24. Before opening: count supplies, set the welcome desk, and confirm group leads. During the event: record shortages and visitor questions. After closing: count returns and write one improvement for the next meeting.

Ask: “Were 24 clay blocks per group enough for the activity, and which step created the longest wait?” Record the answer beside the returned inventory count.

You are welcome to check in at the desk when you arrive. A coordinator can explain the current activity and see whether a group has space and spare clay blocks. If the activity is already full, we can help you observe or find the next joining point.

Avoid guaranteeing a place or a set of clay blocks before checking the group capacity. Keep the reply specific to the east studio session and offer a clear next step: speak with the welcome desk.
