STEM challenges are fun classroom activities that challenge children to use their problem-solving skills. In these activities, children come up with creative solutions that help them complete the assigned task.
Teachers simply provide the needed materials and give their students a 1 or 2 sentence command. The students work alone or in teams to complete the challenges.
STEM challenges are a fun way to help children's intellectual development. Since there is no right or wrong way to use the materials, STEM challenges also boost children's self-confidence.
