At George Mason Elementary, students in Mrs. Dean’s 1st grade class demonstrated their understanding of fractions by creating e-books.  After a brief introduction of the app Book Creator, students were given the opportunity to work on pages of their books explaining different types of fractions and what the fractions represented.  Book Creator then gave them the opportunity to download the book as a PDF, or save it as a movie with them discussing elements of fractions.  Students then took their e-book ‘movie’ and added light background music in the app iMovie.
