Calling all parents, grandparents, teachers, and school Principals. Here is a series of workbooks for all seasons and all reasons. Your significant child, grandchild, or student colors both inside and outside the outlines of letters, digits, and more. The sooner the better he/she learns to think with his/her hands as well as their brain. And it is never too late to begin or resume the learning process. Mastering any skill requires a minimum of 10,000 repetitions. There are no shortcuts in life. Drill, baby, drill. Oh, and these are not just any letters and numbers stamped at random on the pages within. The visual schema has a deep alphanumerical underpinning in the branch of mathematics known as number theory. Yea there is some serious, subtle math going on - which furthermore engages both halves of the brain, and does so simultaneously. It all starts with 117 different, six-letter word squares - one of them per two-page spread of the workbook. Six words across and six more of the same down. A total of thirty-six letters in all per 6x6 grid. The respective pages on the left of each spread have a larger font for coloring just the word square itself during an initial pass through the workbook, while them on the right of each spread have two smaller fonts for subsequently coloring an intricate spin-off. That they are never thirty-six different letters is the first thing the budding mathematician notices. Far from it. Here is the algorithm. Assign the digit '1' to the first letter that appears more than once in the word square. Assign the digit '2' to the second other letter that appears more than once in the word square. And so on. The digits from '1' to '9' are insufficient. After '9' assign the symbols '*', '@', and '#' - a dozen does it. Assign the digit '0' to each of the remaining solitaires. So now we have encoded a word square composed of the letters of the alphabet into the corresponding substitution cipher with the added twist that the latter is composed of the numerical digits - and perhaps some symbols. As you see on the front cover, this is fine fodder for concocting a riveting, revealing representation of the original word square.
