Revised Edition The new training books, expanded to 80 pages in A5 format, are excellent for practicing the arithmetic content of a grade level and reinforcing essential mathematical knowledge. Self-explanatory exercise formats (usually without text) on clearly designed pages make these books an ideal companion for children—both at school and at home. Fun illustrations, coloring pages, and puzzle pages provide enjoyment and variety without distracting from the essentials. Approximately 10 "Bear-Strong Pages" per book serve as a learning progress check for the child, parents, and teachers. The newly developed "Treasure Chests" address calculation advantages that can help solve more challenging tasks, along with various options for self-assessment.
