This is a resource I created and use in both my Kinder and First Grade classrooms. Here are two mini-posters showing students how to distinguish their left from their right (always a challenge for the young ones). It shows a simple way to tell their left from their right. I put these up in the front of the classroom (you might want to put it on your math/calendar wall) on either side of the large board for them as an easy reference. Check them out and see if perhaps they can become a helpful resource for your kiddos as well.
