High-Speed Rail Network Math
Source: Stemoto Original
Students map out a high-speed rail route on the classroom floor with masking tape, simulating a Vande Bharat or Shatabdi express connecting cultural destinations. They program a bot to navigate the route, counting grid spaces to learn addition and time estimation.

Step-by-Step Instructions
Build the Rail Network
Using masking tape on the floor, map out a rail route connecting 3-4 Indian cities. Add station markers with printed cards (Delhi, Agra, Jaipur). Mark grid squares along the route.
Count the Distance
Count the grid squares between each station. Delhi to Agra = 8 squares. Agra to Jaipur = 12 squares. Total journey = 8 + 12 = 20 squares!
Program the Train
Program the bot to follow the masking tape line and stop at each station for 3 seconds (like a real train!). Use the line-following sensor if available.
Time the Journey
Use a stopwatch to time how long the bot takes between stations. Delhi to Agra = 15 seconds. Is that proportional to the distance? Discuss speed = distance ÷ time.
Express vs. Local
Program two versions: an 'Express' that skips a station, and a 'Local' that stops everywhere. Which is faster? By how much? Subtract the times to find the difference.
Why It Works & Notes
Experiential math and geography using spatial mapping and real-world travel concepts. Children learn addition by counting grid spaces between cities, time estimation by timing the bot's journey, and geography by connecting to India's famous rail routes.
