Here's a picture from Distant Shores Media and Sweet Publishing that could be used to represent this week if you wanted to focus on Cain and Abel (we usually use a serpent for this week because of the "Who?" question).
Here's a script for a story we had the kids and staff act out at our church when we did this week to show some of the damage that sin brought. It's the story of Cain and Abel:
Cain and Abel Script
PARTS: EVE, CAIN, ABEL
Eve gave birth to Cain, and said, “I had a boy with God’s help.”
Eve say, “A boy!”
Again she gave birth, to Cain’s brother Abel.
Eve say, “Woo-hoo!”
Abel was a keeper of sheep, but Cain was a farmer.
Abel say, “Sheep, sheep!”
Cain say, “Veggie veggie!”
Cain brought an offering to God of veggies or fruit.
Cain say, “Veggie veggie!”
Abel brought some of his best sheep.
Abel say, “Sheep, sheep!”
God respected Abel and his offering, but he didn’t respect Cain and his offering.
Abel say, “Woo hoo!”
Cain say, “Aw, man!”
Cain was very angry, and the expression on his face fell.
Cain, look really mad and say, “Veggie veggie!”
God said to Cain, “Why are you angry? If you do well, won’t it be lifted up? If you don’t do well, sin crouches at the door. It wants to control you, but you should not give in.”
Cain said to Abel, his brother, “Let’s go into the field.”
Cain, say, “Let’s go into the field.”
Abel say, “Okay!”
Eve say, “You boys be careful.”
While they were in the field, Cain rose up against Abel, his brother, and killed him.
Abel say, “Auuugggghhh!”
Eve say, “Nooooooo!”
God said to Cain, “Where is Abel, your brother?”
He said, “I don’t know. Am I my brother’s keeper?”
Cain, say, “I don’t know.”
God said, “What have you done? The voice of your brother’s blood cries to me from the ground. Now you are cursed because you killed your brother. You won’t be able to grow food and you will be a wanderer in the earth.”
Cain said to God, “My punishment is greater than I can bear. You have driven me out and I will be hidden from your face and I will be a fugitive and a wanderer in the earth. Whoever finds me will kill me.”
Cain, say, “Noooooo!”
God said to him, “Therefore whoever slays Cain, vengeance will be taken on him sevenfold.” God put a mark on Cain.
Then Eve had another baby and named him Seth.
Eve, say, “Awwwww!”
She got some comfort from Seth after losing Abel.
