Spectrum Math, Grade 1 (Little Critter Workbooks)

The nation's #1 educational publisher for grades K-12, together with the well-known Mercer Mayer's Little Critter characters, represents a collaboration of two highly respected "institutions" in the fields of education and children's literature. Like other Spectrum titles, the length, breadth and depth of the activities in these workbooks enable young learners to learn and reinforce a variety of skills about a single subject.
