Gr 3–8— These books utilize popular construction toys with interlocking wooden logs and pieces. In each volume, 37 ideas are clearly illustrated with the added bonus of an instructional CD-ROM for Macintosh and PC computers so children and the grown-ups who assist them can follow along as they build. Projects start with the easiest designs and progress to the most challenging. For some ideas, more than one set of Lincoln Logs™ or Tinkertoy™ pieces is required. The blueprints for the projects (without any text) are excellent with digitally rendered illustrations showing how pieces should interlink and what the completed project looks like. These are books that allow imaginative older kids to work alone and younger ones to have quality time with the adults who assist them. A wide variety of construction possibilities will satisfy readers, including a house, fort, cabin, schoolhouse, tree house, lighthouse, and bridge in Lincoln Logs , and a necklace, airplane, dragster, rocket ship, helicopter, pirate ship, and ferris wheel in Tinkertoy . Welcome additions to craft collections, as well as great gift books when paired with the toys.—Augusta R. Malvagno, Queens Borough Public Library, NY
