Dr. Phillips wrote Easy Grammar texts (Grades 1-6 and Plus) to teach concepts. She first introduces common prepositions and deleting prepositional phrases to help students determine subject, verb agreement, etc. Phillips is also noted for introducing concepts at a basic level and building for understanding--in just two-three lessons daily. She has also added unit reviews/unit tests and cumulative reviews/cumulative tests to promote mastery.
This student test booklet saves you from having to make copies of the tests.
