Take your child's new sight words and write them on a piece of paper using bubble letters.
Then have your child makes rainbows inside the letters of the word. Have your child choose 8 colors and trace the inside of the letters using each color. That is eight times she is writing the letter and practicing the word!
Of course, make sure she is tracing the letters correctly before leaving her to work by herself. And make sure she does the entire word in one color before moving to the next color
