JACOB'S HOUSE is a READ-TO book that becomes a BEGINNING-TO-READ book. It is designed for children 2-6. The age factor depends on ability to concentrate and focus at any particular time. The words are familiar, possibly all being in children's own speaking vocabularies. Number, color, and word games reinforce learning and are fun. For maximum use of the book, an easy parent/teacher guide is at the end. JACOB'S HOUSE is Book 1 of the JACOB SERIES ( 3 books). Koch, an Early Childhood Curriculum Specialist, wrote the books to prepare children for the all important first year of their formal education - THE FIRST GRADE.
