After they were all cut I put 3 letters around them. (I did this with some thinking as to sight words I could make) For instance I wanted to work on 2 letter words so on one noodle I put I, A, U on the other I put T, S N. When you move the letters around you can make the sight words: IT, IS, IN, AT, AS, AN, US, UN. I have flash cards that my daughter would use to help her make the words.
Each letter she would give me the name and sound and then she started to learn the words. We did 2 letters, 3 letters, and 4 letters. :)
I also used some yarn to keep them connected.
