What Four Color Map Puzzle helps students practice
Generate new map regions and shared-boundary adjacency.
Description
Generate new map regions and shared-boundary adjacency. Neighboring regions need different colors; every valid four-coloring is accepted, and a new map changes the actual regions.
Learning Points
- Identify adjacent regions by shared boundaries
- Use four colors while keeping adjacent regions different
- Check a complete coloring through trial and backtracking
Teacher / Parent Note
Begin with a region with many neighbors. Name its shared boundaries, then exclude colors already used by its neighbors; using all four colors is optional.
