Textbooks and materials consume a fair amount of a schools budget. CK-12 Foundation aims to reduce the impact of educational resources needed nationally and globally. This nonprofit organization  provides tools to help increase student learning and engagement by increasing access to learning content. The Foundation has developed the “Flexbook” concept. This is an open-source tool that allows teachers and experts to edit and compile digital textbooks which can then be freely shared within any defined community.
