This sheet can be used many ways, but here is how I use this sheet. My students all have a writing folder which is simply a 12 x 12 piece of construction paper folded. This is stapled inside of their writing folder. Each time they need help spelling a word during their writing, they add that word to the sheet. It becomes an instant reference that they refer back to each time they write and have trouble spelling a word. This has been very successful in my classroom!
