STEM challenges are beneficial to children for so many reasons. These fun and engaging science, technology, engineering, and math activities help kids fine-tune their problem-solving skills, creativity, teamwork strategies, and fine motor skills.
In addition to these benefits, STEM activities also help to reinforce, in concrete ways, children's understanding of abstract concepts that are introduced through books and other classroom media.
These 30 second grade STEM challenges will keep your whole classroom busy and having a great time in the process. Simply provide your students with the supplies listed, present them with the challenge, and let the fun and learning begin!
