Grade 1-5-In his fifth visual math adventure, Tang uses the artwork of 12 famous painters as an aid in developing problem-solving skills through grouping. Each spread features a quality reproduction on the left side. The poem underneath it highlights an item in the picture and presents a math query. For example, on the spread titled "Dancing Shoes," illustrated with Edgar Degas's Ballet Rehearsal on Stage, readers are asked to combine the colorful pictures of varying numbers of ballet shoes on the opposite page into several groups of seven. ("Can you make 7 with these SHOES?/THREE clever ways earn rave reviews!") Clearly written solutions to these exercises are given at the end of the book along with art definitions and brief explanations. This math-concept book is far more appealing than most.
