I find that my 9-11 year olds enjoy being part of the preparation for the church Sunday school lesson. Have them do the following activity for the lesson of Achan’s Sin which in turn encourage the discussion topics as well. 
Bible Story:
Have the students take turns reading the story of Achan’s sin from Joshua 7.
Discussion:
Ask the students if God will notice all sins or just the big sins. Discuss who our sins affect.
Discussion:
Have a class discussion about how others sins affect you. Talk about how you can help others obey God.
Activity:
Have the students write a television ad about why we should not sin. Then have them perform the commercial.
