It’s an adequate, though limited biography of President Obama, designed for early readers, presented in both English and Spanish, illustrated with photos from the president’s life.  Along the bottom of each page, a timeline grows throughout the book, with new dates/events added to accompany the text.  But as a teaching tool, the timeline failed to represent the passage of time with distance along the line:  all dates were evenly spaced regardless of whether they represented a 4-year or a 7-year gap, and some important events described in the text were left off of the timeline, leaving me as a reader wondering why.
