Guided Practice: Unit Launch: Sarah's Inventory Problem

Play through Sarah's month one event at a time and notice which business numbers move first

Phase 3: Guided Practice

Predict Before You Reveal

This is the key student move in Lesson 1: look at an event, make a prediction, then compare it to what actually moved.

How to use the lab

1. Read the event.

2. Predict what changes.

3. Reveal the result.

4. Notice the difference between inventory on the shelf and profit from a sale.

Prediction Lab

Your job:

Before you reveal each event, predict what moves. This is the core launch-lesson habit: do not memorize rules yet. Watch how the business changes.
