B.F.
I don't have anything for you, sorry. But I do have years of perspective.
YOU may have tired of the resurrection eggs but the kids haven't.
I teach the kids that have gone through your class, 1st and 2nd grade.
I ask them to tell me when the first come to my class everything they know about God. One kid kind of summed it up, "He wears brown sandles"!
What I am saying is that repetition is a good thing for the age, although wearing on the teacher. I don't want to discourage you in your teaching. I really want to give you a view of how little they remember at this age.
What you are really teaching is attitude. An attitude of joy, thankfulness, respect and honor, for which, all teachers, spiritual and secular, should show you immense gratitude for the effort and love you put into this.
Thank you!
