In simple rhymes, Tang explains the fundamentals of how each number from 1 to 10 works. His poem "Four Eyes," for example, explains how any number multiplied by four can be merely doubled twice: "Four is very fast to do, when you multiply by 2. Here's a little good advice -- please just always double twice!" He then goes on to explain: "What is 4x4? It's 4 doubled twice. Double once: 4+4=8. Double twice: 8+8=16," and he even provides extra challenge questions below. All of his poems and problems are just as easy (e.g., a number times 6 is tripled, then doubled; a number times 9 is multiplied by 10, then subtracted once), and the book is rounded out with full practice tables in the back.Tang provides children with an excellent lesson, helping them make sense of daunting math without a bombardment of complicated rules. Kids will cheer his winsome presentation, which is wonderfully complemented by Harry Brigg's computer illustrations of animals cavorting around and having fun. Both practical and pleasing, The Best of Times is math that'll help make homework and tests a breeze. Matt Warner
