This preview app lets users access a limited content version of American Book Company's Common Core Math apps. These apps are designed to be used in conjunction with American Book Company's Common Core Math workbooks. For the preview app, a tracker is provided in the front of your American Book Company Common Core Math Preview Copy book. (If you do not have a preview copy book and would like to request one, you may do so at our website: www.americanbookcompany.com.) Utilizing augmented reality, the apps use trackers within the books to display 3D games and a monitor that will work out select examples from the book. These help the student visualize the process of working out those problems in a fun and interesting way. In this preview app, you will find one example of these monitors per grade level available.
