Intro to Tools & Building

Grab your tools, it's time to get building! With this Intro to Tools & Building set, your little can learn how to use tools and build their own workbench. This introductory engineering kit is designed to help develop fine motor skills, mechanical engineering skills, visual-spatial skills, and reasoning and concept development skills.

The perfect set for your young aspiring engineer, it will teach them how to use a hammer, screwdriver, and wrench, and the basic engineering principles behind how these tools work. The kit's large tools are comfortable for your kid's small hands to hold and are also lightweight and safe. In addition to the workbench, they can build five other awesome models with the included modular building parts, including a race car, airplane, house, scissors, and a toolbox. Your mini builder's imagination will run wild as they build their very own creations!

About the Brand

Thames & Kosmos was founded to make science education materials that were more stimulating, effective, relevant – and of course, fun, for kids! Whether it’s building a robot, playing a board game, or performing a magic trick, they strive for their products to empower kids to take risks, experiment, innovate, cooperate, problem-solve, and sometimes even fail. They believe that authentic learning experiences combined with hands-on exploration are a powerful way to captivate curious young minds, and to keep them hungry for knowledge as they continue their journey into adulthood.
