Educators and business leaders have more in common than it may seem. Teachers want to prepare students for a successful future. Technology companies have an interest in developing a workforce with the STEM (science, technology, engineering and math) skills needed to grow the company and advance the industry. How can they work together to achieve these goals? Play may be the answer.

        Focusing on STEM skills is important, but the reality is that STEM skills are enhanced and more relevant when combined with traditional, hands-on creative activities. This combination is proving to be the best way to prepare today’s children to be the makers and builders of tomorrow. That is why technology companies are partnering with educators to bring back good, old-fashioned play.

        In fact many experts argue that the most important 21st-century skills aren’t related to specific technologies or subject matter, but to creativity; skills like imagination, problem-finding and problem-solving, teamwork, optimism, patience and the ability to experiment and take risks. These are skills acquired when kids tinker (鼓捣小玩意). High-tech industries such as NASA’s Jet Propulsion Laboratory have found that their best overall problem solvers were master tinkerers in their youth.

        There are cognitive (认知的) benefits of doing things the way we did as children—building something, tearing it down, then building it up again. Research shows that given 15 minutes of free play, four- and five-year-olds will spend a third of this time engaged in spatial, mathematical, and architectural activities. This type of play—especially with building blocks—helps children discover and develop key principles in math and geometry.

        If play and building are critical to 21st-century skill development, that’s really good news for two reasons: Children are born builders, makers, and creators, so fostering (培养) 2lst-century skills may be as simple as giving kids room to play, tinker and try things out, even as they grow older. Secondly, it doesn’t take 21st-century technology to foster 2lst-century skills. This is especially important for under-resourced schools and communities. Taking whatever materials are handy and tinkering with them is a simple way to engage those important “maker” skills. And anyone, anywhere, can do it.

解析：C。根据题干中的the basics of math and geometry可定位至原文第四段结尾。该处提到，让孩子们在自由玩耍时做一些与空间、数学和建筑相关的游戏，特别是玩积木，能帮助孩子们发现和掌握数学和几何的关键原理。同时，在第四段开头也提到，儿童“先建造，后推翻，再重建”的动手过程会带来一些认知上的优势。由此可知，鼓励儿童动手制作有助于儿童学习数学和几何的原理，故C项为正确答案。

错项排除：文章中未提到与“激发兴趣”有关的信息，A项在原文中无依据，故排除。原文第四段中虽然提到了time和play，但这里讲的是给孩子自由玩耍的时间，而不是陪着他们做游戏，故B项错误。原文第三段提到鼓捣小玩意可以获得一些相关技能，如团队合作、乐观、耐心等，并没有说这对儿童学习数学和几何有帮助，D项错误，故排除。
