This Dolch 315 Basic Sight Words is really a helpful booklet to improve and even increase English sight word list through audio sound. It is particularly designed for kids and all level of ESL learners. First of all, lets explain what sight word is. Sight words (high frequency words) are commonly used words that young children are encouraged to memorize as a whole by sight, so that they can automatically recognize these words in print without having to use any strategies to decode. That is why this Dolch 315 Basic Sight Words is very useful. Furthermore, the advantage for children being able to recognize sight words automatically is that a beginning reader will be able to identify the majority of words in a beginning text before they even attempt to read it; therefore, allowing the child to concentrate on meaning and comprehension as they read without having to stop and decode every single word.
