All-American 1 works well for families who have a range of ages from K or 1st grade through 7th or 8th, if they wish to combine their students in an early American history program. All-American 1 is a combination of both American Story 1 and American Crossing. It pulls together the heart of American Crossing, with its unique Time Travelers resources, with some of best, well-illustrated titles in American Story 1 to provide greater interest and allow for better inclusion of younger students. This program has more books than either American Story 1 or American Crossing. It provides enough resources that parents can use a few of the most difficult resources with older students, while reserving some books primarily for youngers students -- all while working from one guide. This is a great option for allowing a broad range of ages to continue making family memories together!
