Easy Grammar is a mastery-based grammar program. Each grade-level set includes a student workbook and teacher edition, as well as a test booklet beginning in grade 3. Short, frequently reviewed lessons help students retain what is learned. Student workbooks are consumable. The final book in the regular Easy Grammar series is intended for use with students in grades 7-12 and is called Easy Grammar Plus. The Easy Grammar Ultimate series follows Easy Grammar Plus and has grade-level workbooks, teacher’s guides, and test booklets for grades 8-12. Students will complete one page-long lesson each day for 180 days, with previously learned concepts reviewed frequently throughout the year.
