This PowerPoint had 60 slides and includes:
-- What the Constitution is.
-- How old it is
-- Who wrote it
-- Why it was written
-- The Preamble, including what each line of it means
-- The Articles, explained simply
-- The Bill of Rights, explained simply
-- Scenarios to let students apply the Bill of Rights to real life situations
-- pictures and videos (please note that videos are from YouTube and I have no control if they end up being deleted in the future)
I used this presentation with elementary gifted students. They especially enjoyed the scenarios, and we had some great discussions from it.
The PowerPoint is editable for you to adjust it to suit the needs of your students.
