These unique workbooks combine the fun of the Mercer Mayer’s Little Critter characters with solid McGraw-Hill curriculum. The graphics and illustrations that fill each of the 32 pages effectively reinforce the concepts taught. Clear instructions allow for independent learning. Answer keys are provided so parents can check their child’s progress. Perforated pages allow the exercises to be removed for display or to be placed in a progress file. Grounded in solid phonics-based concepts, these workbooks help young learners hone their spelling skills. The PreK and K levels introduce how letter sounds are related to spelling. In Grades 1 and 2, children are introduced to letter patterns, plurals and other word endings, and spelling principles that will follow them through their school years. The engaging illustrations and graphics—all featuring Little Critter and friends—enliven the practice exercises.
