No. You’re correct; the books are longer. You want to stay within your weekly guidelines (see the Teacher’s Manual for page guides at this level) for each unit if you plan to finish in one year. This will probably require choosing fewer books per unit. So, we don’t list as many book suggestions at the Preparatory (6th-8th grade) level for that reason. Some parents plan the history units over 1.5 years, allowing them to cover all of the material twice in middle school. This gives them longer units with more time to read in each unit, but the material isn’t covered as often.
