Code a River Path

Computational thinking skills — sequencing, debugging, and logical reasoning — are essential 21st-century skills introduced naturally through play.

• Framework: IPC
• Unit: Rivers, Rocks & Rainbows
• Learning area: Technology
• Level: Levels 1-3

Objectives

• Create a simple sequence of directional instructions to navigate a river path
• Debug and refine instructions when the path doesn't work
• Understand that coding is giving precise instructions in the correct order

Materials

• Floor grid or large paper grid
• Directional arrow cards (forward, left, right)
• River path map drawn on the grid
• Small toy boat or figure
• Bee-Bot or coding robot (optional)
• Coding worksheets

Instructions

Draw a winding river path on a floor grid. Place a toy boat at the start and challenge children to 'code' its journey to the sea by giving precise directional instructions. Start with unplugged coding — children lay arrow cards to create a path, then test by moving the boat. Introduce the concept of debugging: if the boat doesn't reach the sea, find and fix the error. If available, programme a Bee-Bot to follow the river path.

Educator tip

Start every coding session with unplugged activities before moving to screen-based tools. Physical coding builds deeper understanding.

Assessment

Evaluate ability to create sequential instructions, identify and fix errors (debugging), and use increasingly complex coding concepts.
