I rotate four “investigation bins” during our 20-minute centers — magnets, eyedroppers with colored water, nuts and bolts, and story stones — to support fine-motor, vocabulary, and gentle inquiry. What are you using for sturdy prompt cards little hands can manage — laminated 5x7s on a ring, clip-on photo cues for a TROFAST, or another system — and if you have a printable template, I’m happy to swap my picture-word mats.
