Reward Jar
Tap to drop marbles into a jar as the class earns them, watch it fill toward a goal line you set, and trigger a full confetti celebration the instant the jar reaches its goal.
Built by the AbraCalc team
How to play
- Set the marble goal for your class using the number field at the top.
- Tap Add a Marble every time the class earns one; each tap drops a new marble into the jar.
- Watch the jar fill toward the dashed goal line as marbles accumulate.
- When the marble count reaches the goal, confetti and a celebration message appear automatically.
Set a marble goal for the class, then tap Add a Marble every time the group earns one for good behavior, teamwork, or hitting a target, and watch a colorful marble drop into the jar with a satisfying plink. A dashed goal line marks how full the jar needs to get, and the moment the count reaches your goal, the jar erupts in confetti and a celebration message to mark the reward. Remove a marble if one was added by mistake, or reset the whole jar to start a fresh goal for a new week or unit. Because every single tap counts as its own marble, nothing is ever skipped or lost even if the class earns several at once. Everything runs in the browser with no data saved anywhere.
Frequently asked questions
- What happens when the jar reaches the goal?
- The moment the marble count meets or passes your goal, the tool plays a celebration sound, shows a 'Jar is full' message, and launches confetti across the screen, giving the class a clear, visible payoff for reaching their target.
- Can I undo a marble if I tapped by mistake?
- Yes, the Remove One button takes away the most recently implied marble and updates the jar and count immediately, so a stray tap or an accidental extra doesn't throw off the class total.
- Does changing the goal empty the jar?
- No, changing the goal number only moves the dashed goal line and re-checks whether the current marble count already meets it; your existing marbles stay in the jar unless you tap Reset Jar to start over.
