These updated AI2 Maker Cards are a refreshed version of the originals found on the MIT AI2 website. I carefully revised the content to fix errors and redesigned the layout to be clearer, more student-friendly, and easier to follow. These improvements make the cards a smoother, more effective resource for teaching and learning with AI2. If you teach PLTW App Creators, I highly recommend using these to familiarize your students with App Inventor before starting the App Creators course.
