Some teachers like to fill jars with marbles (or other items) as their students meet important goals or do good things. Once the marbles in the jar reach a certain level, the class earns a prize or incentive from the teacher. classjar is a simple static web-app that helps with that.
- Step 1: Create your own copy of this Google Sheet.
- Avoid changing the column headings (date, size, desc).
- Step 2: Get (copy) a public share link (i.e., "Anyone with the link can view") for your newly copied Google Sheet.
- Step 3: Access the live version of classjar here.
- Step 4: Paste your public share link into the live version of classjar and fill the jar!
- Step 5: Implement, explain, announce reward, change sheet as appropriate (remove demo entries, etc).
- Using a marble jar reward system can sometimes be a helpful classroom management strategy.
- This strategy is discussed in several popular teacher training manuals (e.g., Teach Like a Champion and First Days of School)
- I thought it would be cool to create a web-app version of the marble jar reward system. Here's what it does:
- Pulls data from Google Sheet with three columns: date, marble size, and description of positive thing.
- For each row in the classjar google sheet, the app drops a marble in the jar.
- Circle (marble) radius set as multiple of size column on Google Sheet.
- Click on any marble to see more info about how it was earned (date, description of positive thing).
- It's up to the teacher to decide on an incentive earned when the marbles reach the reward bar (finish line).
- Marbles have physics!
- If you knock all the marbles out of the jar -- just reload!
- Basically, a data visualizing thing -- Visualize a Google Sheet that tracks positive classroom behaviors as a marble jar!
