Write the scripture reference of each plague on one color of index card and lay them face down. On a different color card, write out the ten plagues. Place these face down also. Make the game harder for older kids by omitting the color differences and mixing the cards face down. Take turns turning over a card. If it is a reference, look it up. Try to turn over the matching plague for that reference. If you get a match move the pieces to a timeline that puts the plagues in order. Continue playing, using the Bible to look up as many as you need to look up. Try playing again to see if they can remember any of the references. Remind your students that God was patient with pharaoh, but pharaoh was too stubborn to listen to God when Moses told him what God had said. Praise the kids for their digging into the Bible for answers.
