many words they see all the time because those words follow the rules of phonics, such as in, hat, and bed.
But some words don’t sound like they’re spelled — words like of, to, and was. If kids sounded them out, they might pronounce them “off,” “toe,” and “wass.” Or if they tried to spell them, they might guess “uv,” “too,” and “wuz.” Since these words don’t follow the rules, kids need to learn to recognize them automatically.
Sometimes sight word lists are color-coded to show which ones can be sounded out. Words that follow spelling rules might be in green. Tricky words with irregular spellings might be in red.
