Sight words, also known as frequency words, are common words that appear again and again in children's reading materials. Knowing them by sight is essential for reading fluency. Each card in this set includes a sight word commonly taught in preschool or first grade. The Science of Reading demonstrates that young readers need to encounter letters, sounds, and words many times to develop automaticity: the ability to read quickly, accurately, and effortlessly. This set of cards, with its convenient box, is a fun way to practice sight words and develop reading automaticity, both at home and on the go.
