As a First Grade teacher I can tell you that Color Coded Sight Words (Fry Words) save my life! When a student asks me how to spell the word "like" for example I can say "It's on the word wall, under the letter L and it's pink." My kids do such a better job finding the words on the word wall and helping each other spell words.
This is the FIrst 100 FRY words.
Each group of 25 words are given their own color.
