FIRST LEGO League Challenge Programming
There are several ways of programming FIRST LEGO League Challenge Robots. The most popular new language created by LEGO Education is based on Scratch called Word Blocks. A version of this Scratch-based language called EV3 Classroom is also available for those using EV3 sets rather than SPIKE Prime. LEGO also provides a special version of a line-by-line language called Python for programming robots.

SPIKE Prime Software
SPIKE Prime Word Blocks (Scratch)
The main programming language for SPIKE Prime is called Word Blocks, which is based on Scratch. LEGO Education provides an online introduction to the set and its software. The software app can be downloaded and installed before or after receiving the SPIKE Prime set.
- SPIKE Prime App Version 2 (2022 version)
- SPIKE Prime App Version 3 (latest version)
- This new version of the app includes a variety of improvements but also reduces the number of choices for Movement blocks.
- LEGO Education description of SPIKE Prime App Version 3
- Youtube video about the changes in App Version 3
- Slides showing how to convert Movement Blocks from App Version 2 to Version 3
- If you upgrade to App 3, it will update your hub to new firmware that works with App 3.
- If you decide to go back to App 2, you will need to change the firmware back to a version that works with App 2. See this link for a method of doing so.
- Lesson called "Guided Mission" that includes sample program for one of the 2023 MASTERPIECE missions
Season-Independent Lessons Using Small Printable Mat
One of the best ways for team members to learn how to program a LEGO robot is to have simple challenges with guidance on how they might solve those challenges. And, these challenges can performed on a 2x3 foot mat, allowing small groups or individuals to learn the skills they'll need for the annual challenge on the full-size mat. With this in mind, ORTOP has developed a set of simple lessons that feature such challenges that are backed up by short videos that give hints on how to solve the challenges.

Videos for team members on programming a SPIKE Prime Robot
Episode 1: Introducing Eva the parrot and Eaglet the baby LEGO eagle.
Episode 2: Eva arranges for Eaglet to get a ride home while we learn more about programming turns.
Episode 3: Eaglet finds his lost cat while we learn how to use the built-in gyro to control the robot's turns.
Episode 4: Eaglet brings his lost cat home while we learn how to program an attachment for retrieving cats.
Episode 5: Eaglet's Chariot robot learns how to drive in the middle of the road while we learn how to program a color sensor.
Episode 6: Chariot makes a better turn to Yellow the cat as we use our gyro programming skills.
Episode 7: Chariot stays in the middle of the road while we learn how to use a color sensor to follow the edge of a line.
Episode 8: Chariot uses a motor's built-in rotation sensor to measure distance while it uses line following to stay in the middle of the road.
Episode 9: Eaglet visits the Animal Shelter with the help of his Chariot robot programmed using a My Block.
Episode 10: Chariot delivers food to the Animal Shelter while we learn how to use a variable to count stripes to improve the robot's navigation. We also learn more about use My Blocks as well as how to display numbers on the top of the hub.

Mindstorms EV3 Software
Mindstorms EV3 Classroom (Scratch)
Mindstorms EV3 Classroom is a graphical programming language for the Mindstorms EV3 sets. It became the standard software for the EV3 Set for those running PCs with the 64-bit version of Windows 10, Chromebooks and Macs using macOS Catalina 10.15 in the fall of 2020. The Mac version also works with macOS Mojave 10.14. Those with earlier operating systems should continue to use EV3 Lab.
EV3 Classroom is based on an educational language called Scratch and is quite similar to Word Blocks, the graphical language provided by LEGO Education for its SPIKE Prime set. LEGO Education has also announced that EV3 Classroom will become available for and Chromebooks.
