This is a resource that my students keep in their writing folder during writing workshop. All of my districts k-1 sight words are included and there are blank lines for extra words to be added.
As these words are introduced- I have my students highlight the word. You can highlight any color but I have my students highlight the words green if they are words that can sounded out, yellow if they are words that have a chunk or rule and pink if they are irregular words like "of".
If students ask me to spell a word and it is not in the Writing Words book- I will write it on a scrap piece of paper after a student tries to spell it on their own on a scrap. Finally the student will write the correct spelling in their book.
I copy mine 1 to 2 sides and hole punch them so that I can place it in their writing folders.
