Fill In Puzzles
Satisfy your craving for number fill-ins with this sure-to-please puzzle book. 60 pages of puzzles with one puzzle per page and the solutions at the end. Number fill-ins teach deductive reasoning and are also good for maintaining visual acuity and manual dexterity. The book is small enough (6x9 inches) to slip into a purse or briefcase, but still large enough for you to easily complete the puzzles.
The first 18 puzzles have one of the numbers already filled in to help you get started. After doing those, you should be sufficiently skilled to start the puzzles on your own.
