Engage students at the start of their coding journey.


Engage students at the start of their coding journey.


Keeping students engaged: Younger learners need interactive, hands-on experiences to stay motivated.
Classroom tech constraints: Many students can’t install software or use complex developer tools.
Scaling feedback: Reviewing every student’s code takes too much time, especially with large or mixed-skill classrooms.
Coding sticks when students can experiment, see results, and have fun along the way.
