Learning sight words is an essential part of gaining the ability to become an independent reader. I have been using these wonderful printables found at www.havefunteaching.com for my 4 year old daughter to practice her sight words. Every time she knows a word we highlight the word. Once she can read a whole column of words, she gets a sticker on that column. When she is able to read a whole page of (100) sight words, she gets a certificate of completion.
