STEM Bins®
What are STEM Bins®?
STEM Bins® are hands-on, play-based engineering and problem-solving activity kits designed for elementary students (Grades K–5) to use during morning work, early finisher time, or classroom centers.
Each bin holds one simple building material plus challenge cards. Students grab a bin, pick a card and build. Brooke Brown created STEM Bins® in her own classroom.
