It is believed this Grade 4 Vocabulary List to be the most unique and efficient reading vocabulary list developed for upper elementary level students. As research (and common sense) shows reading comprehension functions at peak efficiency when vocabulary and fluency are present, it is imperative these words be memorized completely. When this is achieved, comprehension of upper elementary reading material and standardized test questions will improve dramatically. There are a total of over 800 new words introduced in this 4th grade vocabulary list (including heading titles) and is designed as a continuation from our Grades 1- 3 Reading Vocabulary Lists which contain the 2000 Most Common Reading Words used in average reading material. If a student can master this list (along with our 2000+ Vocabulary words in the Grade 1-3 List) all academic areas which require 4th grade level reading skills, including standardized tests, will improve markedly. The words used in our Grade 1 to 5 Vocabulary List have been carefully selected as the high frequency words typically used in reading books and standardized tests. The flash cards are presented on 6 cards per page so users will have to cut each page into cards along the black lines to be used as individual cards with their students.
