What Are LEGO Challenges?
LEGO challenges are open-ended building prompts encouraging kids to think outside the box. Unlike step-by-step instructions, these challenges give kids a problem or theme to build around, helping them strengthen their creativity, logic, and spatial thinking.
They’re ideal for structured and unstructured play and can be easily adapted for individual, group, or classroom use.
This calendar encourages STEM thinking, problem-solving, and imaginative play. It is perfect for kids at home, in the classroom, or in a LEGO club. Whether you’re stuck inside on a rainy day or planning a screen-free week, these LEGO challenges are just what you need to spark creativity.
