Put these high quality sensory/storage bins to work all over your learning environment. Use them to store materials and loose parts, fill with sand/water and tools, flip them over and use a temporary block platform, keep materials for rotation neatly tucked away, trap balls and rolling items at the end of ramp courses, give the baby dolls a bubble bath, and that's just the beginning. Each of these indispensable bins comes with a loose fitting lid that can double as a tray.
