With the exception of Kindergarten, the texts are designed so that a majority of the time is spent on the major work of the grade.  Kindergarten does not spend daily time on counting and cardinality.  The series gives students extensive work with grade-level problems.  There are some assessment items from future grades, however, because of the number of test forms and the online test generator (allowing teachers to pick items and create their own assessments) those items can be replaced with grade level items.

The texts provide a majority of the time on the major work of the grade.
