Revised Edition: The new training booklets, 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 exercises (usually without text) on clearly designed pages make the booklets an ideal companion for children—both in school (for example, for 5-minute training or differentiated instruction) 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 booklet serve as a learning progress check for the child, parents, and teachers. The newly developed "Treasure Chests" address calculation advantages that can help solve even trickier problems.
