This book was read to me in the mid/late 1990s, in Ohio. I believe it had a yellow cover. The girl was struggling with learning her right and left hand. She was in a parade (or maybe marching band?) and turned the wrong way from the rest of the group, and I think marched alone for a while. In order to remember it for the next time, someone gave her a red ring to wear on her right hand. Then she marched with the group the next time without issue.

The cover is yellow.
