Lego Space Challenge Cards for kids.Pin

LEGO is one of the most excellent and versatile play materials out there. He has been in love since my son connected his first LEGO bricks. Usually, we enjoy tons of cool science experiments together, so here we have mixed science and STEM with LEGO building ideas.

Why Use LEGO for Hands-On Learning and STEM?

For several reasons, LEGO bricks are perfect for hands-on learning and STEM (Science, Technology, Engineering, and Mathematics) education for kids. First and foremost, they encourage creativity and problem-solving. By providing a medium for kids to build and experiment, LEGO bricks enable kids to explore their imaginations and find innovative solutions to various challenges.

LEGO sets often have detailed instructions, allowing children to follow step-by-step guides to create complex structures. This helps them develop their ability to read and understand technical documents, enhancing their spatial awareness and logical thinking.

These LEGO task cards do include instructions for kids to follow!

Moreover, LEGO can teach various STEM concepts, such as physics, geometry, and mathematics. Kids can learn about balance, friction, and gravity while constructing and testing their creations. They can also use LEGO to study concepts like symmetry and patterns, making learning more engaging and hands-on.

The LEGO task cards below are fantastic for exploring math, symmetry, and patterns!

Collaboration is another key advantage of LEGO bricks. Kids can work together to solve problems, share ideas, and build projects as a team, promoting important social and communication skills.

  1. Hi!
    I love all of your activities and they are especially great to have during this time. I was wondering if the space activities were meant to create 2D builds or 3D. Do the kids just lay out the bricks in the patterns on each card? Thank you for your help and for all of these fun activities! 🙂

  2. Hi Betsy!

    That’s the beauty of the cards! To start just laying out the bricks works well. However, taking the challenges to various levels is what it’s all about!
