Mardi Gras is on Tuesday and we like the tradition of Kings Cake for Primary.  (it's called the Kings Cake because of the 3 Wise Men who came looking for the baby Jesus) We've included a template on how to make paper slices of cake.  Make about 9 slices to make a whole cake.  Decorate them cute and put little plastic baby's inside 2-3 of them (we bought our baby's at Walmart).  You can put taffy or an inexpensive piece of candy in the other slices.
Choose a child to come and pick a piece of cake.  If they choose a slice with a baby inside they can pick their favorite song to sing.  If they choose a slice with a piece of candy, then review the song you are working on.
