Welcome to the Steck-Vaughn Core Skills: Reading Comprehension series! You have selected a unique book that focuses on developing your child's comprehension skills, the reading and thinking processes associated with the printed word. The stories are comprised of words carefully chosen from the Dolch Basic Sight Vocabulary and the Kucera-Francis word list. Words that appear most frequently in primary reading basal series were also used. This vocabulary list does not include every word students are expected to read in the stories, but rather is a list of words that are introduced as new vocabulary and defined.
