Humphrey the horse counted himself. One horse. Humphrey said 'NEIGH!'"" And, to start this off, Peppe sets down the equation 1 x 1 = 1. Then Humphrey encounters two pairs of cows (2 x 2 = 4), three groups of three pigs (3 x 3 = 9), and so on up to twelve groups of twelve mice. For each operation Peppe furnishes the equation, a row of circles containing the numerals from 1 to 12, a corresponding row of squares showing their product for the featured multiplier (4, 8, 12, etc., to 48 on one page; 5, 10, 15, etc., to 60 on the next), and thumbprint pictures of the appropriate number of animals, all black and white except that every fourth (on the 4 x 4 page), fifth, or whatever is filled in with a different color. Sound complicated? Maybe that's why it won't work as an early-grade introduction to multiplication. Except for a small-print, adult-level notice on the CIP page, there's no explanation of what's going on. Except for the unexplained rows of circles and squares, there's no indication that multiplication is not necessarily a matter of square numbers. Nowhere are there words or activities to point up the concepts, such as the Crowell Young Math series provides. In short, there's nothing to guide a child without a teacher and nothing a teacher couldn't do better without.
