“Children in first grade should not be given lists of sight words to memorize. They should be learning to decode (sound out) and encode (write) regularly spelled words, NOT MEMORIZE THE VISUAL APPEARANCE OF WORDS.
First graders should be learning to identify the sounds in words they say and link letters to those sounds. This is called phoneme awareness and phonics, and these are the critical skills for becoming a good reader. Your first grader should read words like GO and SEE by knowing the sounds that those letters stand for, and sounding out the words. As he does this often, his brain will start to automatically recognize the words. This will enable him to sound out and read or write any regularly spelled word independently. He will not have to visually memorize lists of words, except for those few that are “outlaw words” (don’t follow the rules), and he should only tackle these after he’s mastered phoneme awareness and phonics.
If he is not learning phoneme awareness and phonics at school, teach him at home. Try asking him to read some nonsense words like MUN or SAF. If he can’t do this, ask his teacher whether she is teaching him to sound out words. If you want him to be a good reader in second grade, teach him these skills NOW yourself. There’s lots of good information on the web about how to become aware of the sounds in words and link those sounds to letters.”
