According to Reading Rockets, a valuable literacy website, only 850 common words account for 80% of the vocabulary elementary school children use in their writing. It follows then, that learning to spell this relatively short list of words can make writing much easier for children. This is especially true given that the most common words are used up to 13 times more frequently than the less common ones.
Reading Rockets organizes this list of 850 words by grade level. Find the appropriate lists for your children and help them learn these words. And some day maybe they’ll write a note to you to thank you for your efforts.
