Worktexts Worktexts, a combination of a workbook and a textbook, contain instruction, questions, projects, and exercises in a consumable workbook. Worktexts are available from Christian publishers that incorporate a Christian world view. These curriculum materials have similar, although usually less extensive, content to traditional textbooks. They may require less time to complete. Typically there are five subject areas with 10 booklets each per grade.
Answer keys are available as well as other supplemental materials.
Diagnostic tests show where a child should start in each subject, which is useful for children coming out of a school setting. The idea of unit studies is that knowledge is learned and remembered better if presented in a connected way. Unit studies also provide interest and motivation. Several subjects are centered around a common theme or project in each unit. For example, a theme such as attentiveness or light may be chosen and related material for study selected from history, science, literature, and Bible.
