Opening Drill: Have the play Random Dice, and have them experience success of failure with no control over the outcome:
Continue to have the winner play those in the class who have not played yet. When you are done, make a big deal about how awesome the winner is.
4) Ask them if there is anything in their lives today that they have they did not earn, but they did participate in. You will get strange answers, and you might get some to point out salvation. (I have given an example of the difference between earn and getting with respect to God's interaction in our lives, and you can read that by clicking here.) Once you have played this out, get them to understand that Salvation is a unearned Gift, that they have to accept, but they have no reason to think they have earned.
If you get other ideas, don't reject them, just let them talk it out.
Teaching Psalm 107:1 - (NIV1984): "Give thanks to the Lord, for he is good; his love endures forever."
Read them the Verse.
Now ask them if they know anyone who is Good all the time.
God is the only answer.
Thanksgiving Craft: If you have the time, you can download this coloring craft, the card shown above, by clicking HERE.
Print this 4 cards per sheet on white card stock, and cut it into quarter. You can also send it to Staples or some other printer, having it printed on white card stock, cut in quarters. You get 4 cards per sheet.
If you have many teachers and students, break into groups, and have them talk about things they are thankful for, and how God allowed that to happen in their lives. If you want a story to explain how thankfulness can be done wrong, I have written a explanation about this very verse, and you can read it by clicking HERE.
Then have them color their cards.
