Want to challenge children to use STEM skills to actively overcome challenges and to solve problems using supplies you already own? The goal of 10 STEM Building Block Challenges for Ages 3-11 is to challenge kids to solve problems that mimic real-world challenges. We have designed 10 STEM Building Block Challenges using building blocks in addition to household supplies. Each Challenge presents a supply list, a problem, and a challenge. Each problem is a real-world problem faced by STEM professionals and the challenge turns the problem into challenges children can solve using building blocks and requires children to design and construct structures within specific creative constraints. We want to prepare our children to step into STEM professions and STEM college majors with skills such as design, redesign, confidence, risk-taking, and collaborative efforts. These 10 challenges will prepare children to overcome problems and to understand the beauty of failing, rethinking, redesigning, and asking for help. We included art as well!
