Vocabulary plays an important part in learning to read. Beginning readers must use the words they hear orally to make sense of the words they see in print. Kids who hear more words spoken at home learn more words and enter school with better vocabularies. This larger vocabulary pays off exponentially as a child progresses through school.

Vocabulary also is very important to reading comprehension. Readers cannot understand what they are reading without knowing what most of the words mean. As children learn to read more advanced texts, they must learn the meaning of new words that are not part of their oral vocabulary.

The National Reading Panel (2000) concluded that there is no single research-based method for teaching vocabulary. From its analysis, the panel recommended using a variety of direct and indirect methods of vocabulary instruction.
