Excellent Book. Well-Written Instructions with Clear/Well-Illustrated Drawings. This is a BOOK that PROVIDES FUN, USEFUL PROJECTS. These are PROJECTS that DOUBLE AS GREAT GIFTS, all the while "SNEAKING IN" OPPORTUNITIES to Develop/Build Skills in READING/FOLLOWING INSTRUCTIONS, Attending to the IMPORTANCE/RELEVANCE of SYMBOLS (which requires the use of The Symbol Guide/Key), Attending to PATTERNS in Construction, Developing MATHEMATICAL CONCEPTS and Using CRITICAL THINKING SKILLS. This is a FIVE (5) STAR BOOK! A+ ( THIS BOOK ALSO EARNS A GREAT BIG SMILEY FACE FROM A VETERAN TEACHER ! )
