What about asking the kids? You could ask children to tell you what was the most important thing they learned in X grade then select one or two to use in the yearbook.
Does anyone know where I would be able to find sayings for K - 5th grade. Just a line or two about each grade. I am looking for ideas to put in our yearbook and thought a saying at the bottom of each grade's page would be neat. Thanks for any help you can give. . .
