This revised version of "Mathematics for Horticulture" was developed to meet the needs of educators faced with teaching a mathematics curriculum based on real-life applications. The manual includes a wide range of topics, some remedial in nature, but all very basic to success in the industry. The manual contains seven chapters that cover the following topics: (1) measurement; (2) geometry for the landscape; (3) sales; (4) construction; (5) grass seed mixtures, sod, fertilizers, and chemicals; (6) using drawing scales and writing estimates for landscape plans; and (7) producing a crop for market. Each chapter includes information sheets, examples, and a variety of practice sets that can be used for student review or testing. Sample blank forms are included for writing sales receipts and for writing estimates for landscape projects. A separately bound answer key is included with the student manual. (KC)
