We use a star chart to encourage positive behavior and good habits. When one of the kids earns enough stars to fill up the chart (30) they are rewarded with a Roblox gift card. We usually have a few $10 physical gift cards posted by the star chart. It keeps all 3 motivated seeing the reward every day. We ran out of gift cards and my niece had gone the extra mile volunteering to do extra chores and earned enough stars for a reward. I bought this digital gift card and she had her reward loaded to her roblox account in a matter of minutes. Easy peasy chicken squeezy!
