The Canadian Bible Society has some freebies: Bible Quiz, e-cards, Daily readings, History Bits and more, but I really enjoyed the e-scriptures; interactive Flash scripture movies. Available in English and French.
You won’t want to miss these if you are teaching younger children:
Free Bible Story Activity Ebooks. Each story includes a coloring page, word-search, crossword puzzle, and Bible quiz with memory verse.
