| PreSchool-Grade 2-This picture book tells a story and reinforces the concept of addition. The lively watercolor illustrations serve both missions well. While on the road, a female truck driver and a dog are passed by many other vehicles loaded with various animals. As their journey advances so do the math problems, going from the simple "3 + 2 = 5" to the final "9 + 0 = 9." However, there is no logical progression in the examples provided; why does "6 + 1 = 7" follow "3 + 2 = 5?" The text is told in rhyme, which adds to the sense of movement but it is rather singsong. All of the characters end up at a carousel (made from the drivers' freight) and the final illustrations capture their joy and excitement. The book ends with a two-page spread of suggested activities for kids and adults. The "Level 2" designation suggests that this is designed for ages 6 and up but the simplicity of the story and rhyme as well as the juvenile nature of the illustrations would be more appealing to a younger audience.

Foreign Customer Review / 国外客户评价: |
| I disagree with the last reviewer. As a first grade teacher, I liked that the number sentences demonstrated the commutative property (could that be why the author had the animals commuting? LOL) Our class could discuss how the sentence 5+2 is the same as 2+5 for example - regardles of which group on what truck was counted first the total animals is the same. We could make trucks and put our own little animal on them, and write our own # sentences in our own little books - changing the order of the trucks and getting the same result. (Part-part-whole concept.) A child shouldn't be taught that adding two quantities works only one direction and it's either right or wrong based on the direction you write the # sentence. 5+2 =7 is the same as 2+5=7. Even 7=5+2 or 7=2+5 is correct! I appreciate that that the numbers are commutable in this text!
