In this entry in the MathStart series, Murphy (Lemonade For Sale, p. 1711, etc.) uses an engaging tale about an amateur dog show to present the concept of ordinal numbers and how they are an integral part of daily life. Readers observe as each dog is called forth for its particular feat; seamlessly woven into the text are the first, second, third, and fourth ordinals. ""'Today, you will see tricks performed by the most talented dogs on the block,' announced Jeremy. 'Maxie, you're first.' ""When a new ordinal is introduced, Nash provides a diagram that has each of the four numerals situated below a mug shot of the dog they represent and highlights the featured digit in red. His vividly hued, lively illustrations humorously depict the antics of the intrepid canines and their proud owners. The combination of written and visual reinforcement effectively provides a firm foundation of understanding for beginning learners.
