Start with age, not with a product name
The Learning Pathways page tells Petersburg families to read age fit before they open a cart. Discover Builders covers ages 6–8: motorized creatures and simple cars, gears and pulleys, and intro line-following with visual blocks. The student who fits is new to robotics, likes LEGO-style parts, and needs quick wins. Foundations Robotics covers ages 8–10: obstacle-avoiding bots, Bluetooth remote vehicles, and basic programming logic. The student who fits is ready for more than pure building and can read short instructions.
Code & Build covers ages 10–12: Python on microcontrollers, a robot with an arm and a drive, and sensor demos. Skills named there include debugging and electronics fundamentals. Challenge League covers ages 12–16: competition-style drivetrains, autonomy basics such as line following, and showcase presentations. The teen pathway expects feedback, iteration, and sometimes mentoring younger students. None of those four names is the thing you purchase. The pathways page says each one describes skills and projects, then points you to a program page and the Program Catalog.
