Here is a fun idea that will drive them into Leviticus 11. Make a dual sided copy of the pages here and fold it to look like a restaurant menu. Have a menu for each of your students. Then simply have them follow the instructions inside. Once they have made their selections, read Leviticus 11 together to see if they made the appropriate Kosher selections. For a prize to those who guess correctly, have something Kosher like a pickle.
When giving a worksheet like this, I like mixing up the class and giving them a partner to work with that they might not usually work with. Then after a set time go through the answers as a class and make sure and take time to focus on the big life changing, take home principles. On the third page is some the key to the comparisons between Joseph and Christ.
