Description

In this activity, Cubs will learn about coding concepts like sequences and algorithms by creating instructions using Lego bricks. Each sequence of bricks represents a set of instructions that others must follow, similar to how computer code works.

Resources

- Large quantity of Lego bricks in various colors
- A printed key showing what each color brick represents as an instruction
- Paper and pencils for planning sequences
- Container to hold Lego pieces
- Small prizes for completed challenges (optional)

Instructions

1. Set up the base stations: Divide the Cubs into two groups of 10 and set up the Lego base. Provide each group with plenty of Lego bricks (ensure you have at least 6 bricks per Cub in various colors).
2. Introduce coding concepts: Explain that computer programs work by following a sequence of instructions in a specific order, like a recipe or a map. The Lego bricks will represent these instructions.
3. Demonstrate a simple flow chart: Show how a sequence of Lego bricks can represent a set of instructions. For example, a red brick means "turn right", a blue brick means "move forward", a yellow brick means "pick something up", etc.
4. First challenge - Simple sequences: Each Cub creates a simple sequence using 6 bricks. Their partner must follow the sequence exactly as laid out, performing the action associated with each brick.
5. Second challenge - Flow chart: Have Cubs create a more complex flow chart with decision points. For example, "If the path is blocked, use the green brick instructions; if not, follow the yellow brick instructions."
6. Final challenge - Group sequence: The whole group must create one long sequence together, with each Cub adding one instruction. Then watch as one volunteer follows the entire sequence.
