ONTARIO: THIS LAND Leslie Asseltine, John Kolger and Barry Preston. Toronto, Fitzhenry & Whiteside, c1983. 92pp, paper, $5.95. ISBN 0-88902-463-4. Grades 4 and up. Reviewed by George Gereben. Volume 12 Number 1 1984 January Written by three environmental studies consultants with the Waterloo County Board of Education, Ontario: This Land is specifically designed for use at the elementary level. The book deals with many aspects of the province, past and present, and how to present them to students. It is not written as a straightforward text, but rather as a supplementary teacher's aid to help keep students interested in the subject matter. In keeping with the idea of presenting the province as a whole subject, the book incorporates a number of subject areas, math, English, science, geography, history, and current events, into each aspect of the province as it is discussed. In discussing housing, for example, science is represented in the form of an insulation experiment, history in the housing of native peoples and early settlers, and biology in the homes of animals. Letter writing, pamphlet making, figuring time and distance, and English are all used in the section entitled "Ontario A Place to Visit." The students can use any one of these skills as they look at different areas of the province and discuss why they would like to visit there, what they would see, or how to encourage people to visit, after researching the idea, their own home towns. Many sections also have vocabulary lists and crosswords to help keep the students interested and improve their language skills at the same time. The book does not fall into the common trap when discussing the province that many do. Ontario: This Land looks at the entire province and not just the southern part, making it useful to teachers all over Ontario. Ontario: This Land is designed for the elementary level but not for one particular grade or level. It has various exercises that would be helpful for teachers from grades 4 to 7. It would be a useful supplementary tool for the established teacher looking for new ways to present old ideas as well as for the new teachers approaching the material for the first time.
