Smiley Sight Words teaches high-frequency sight words to your child! The 1,600+ sight words included with Smiley Sight Words comprises up to 85% of the text in a child's early reading materials. A child who can recognize just 8 of 10 words in a sentence can typically understand its meaning! "Sight words" often cannot be illustrated via simple pictures or sounded out according to regular phonetic decoding rules, thus they need to be learned and recognized "on sight". Smiley Sight Words is a handy way to keep track of and encourage a child's mastery of their sight words.
