The Early Reading Comprehension workbooks (Books A–D) are for young readers, specifically grades 2–4. Reading Comprehension (Books 1–6) targets grades 3–8, and MORE Reading Comprehension (Levels 1–4) is designed for junior high and older students.
The entire Reading Comprehension series is particularly useful in a classroom that has students of varying reading abilities. The consistent format allows students in the same class to use different levels in the series. Students gain confidence and increase their reading, language, and comprehension skills as they progress through the series.
