Class marble jar v0.2.0

A whole-class reward jar on the projector: pick a goal, add a marble each time the class earns one, and celebrate when it reaches the line. It only fills, never empties, and it is always the class’s, never one child’s. Team jars with made-up names if you want them.

How to use it

  1. Pick a goal: 20 marbles is about two weeks in most rooms.
  2. Add a marble when the class does what you asked: a quiet line, a quick tidy-up, kind words.
  3. When it fills, celebrate together with the reward you agreed on, then start a new goal.

Ideas for class

  • Agree on the reward with the class before the first marble.
  • Add, never subtract: a jar that loses marbles turns into blame on the children who slipped.
  • Say out loud what earned the marble, so the class knows what you want more of.
  • Use team jars for table groups, and fill them all toward one class celebration.

Questions

Can I take marbles out?

No. The jar only fills. Taking marbles away tends to turn the class against the children who cost them, so the only way back to empty is Start a new goal.

Is anything saved?

The jar’s count stays in this browser, so it is there tomorrow. Nothing is sent anywhere and there is no name to type.
