Little Engineers 2025
The full run at Shidong Elementary, built on the FLL SUBMERGED 2024-25 season.
Home Curriculum
We are a nonprofit, so there is no reason to keep any of this behind a door. The trainer our students learn on and the slides our volunteers teach from are both published here: for teachers, for schools we have never visited, and for any group that wants to run the same day themselves.
The trainer
A bilingual SPIKE Prime trainer we built ourselves, because nothing we could find taught block coding in 繁體中文 at the level a Taiwanese child actually needs. Children learn it here, then apply the same program to the physical robot. Our teaching is built on FIRST LEGO League, and the mission challenges come from the current season.
New: version 2
Version 2 wraps the trainer in a game-style learning path. It is in English only for now, while version 1 stays fully bilingual.

Classroom slides
These are the actual slides used on the day. There is one deck per school or trip rather than one per topic, because that is how we build them. Open one, or take a copy into your own Google Drive and change whatever you need.

Seven weekly sessions at Tianmu Elementary, 23 April to 4 June.
The full deck our volunteers taught from at the Tainan summer camp.
Video
We use this in sessions to introduce the season before the children start building. It is on our YouTube channel, so you can use it in your own classroom exactly as we do.
SUBMERGED is the FIRST LEGO League season set on the ocean floor, and the missions on our mats come straight from it: releasing a sample, raising a mast, moving a shipwreck without knocking it over. Watching the season film first means the children know what the models on the mat are meant to be before they are asked to reach them, which saves explaining it twice.
Tools we built
RoboCoach is an AI-powered Chrome extension that helps FLL teams learn to program faster and more independently, with instant guidance, debugging help and step-by-step explanations. We built it after pastors we trained in rural Taiwan told us coding was the hardest part to teach. It now has more than 200 monthly users in five or more countries, including Taiwan, Vietnam, Korea, Germany and the United States. At the request of the mentors we trained, we also made Mandarin FLL video tutorials on SPIKE Prime control and sensors.
