This unit was created to accompany the Heinemann Continents books to reinforce and test comprehension, and to expand on geography and map reading skills. These books are great for an introduction to continents for primary grades or review for elementary level and are available in most public libraries. There are worksheets for both primary and elementary level. Suggested use for primary grades is in conjunction with a continent unit and reading of the book over a period of several days. Elementary students can read the whole book in a day and complete the worksheets for each book in one day.
