This center includes 40 sight word sentences. There are four sets of 10 different sentences. I like to color code the centers so they can be sorted easily, so I would copy the sets on different colored card stock. The center can be used different ways. I included period and question mark cards that can be matched (using velcro dots)to each sentence, or, dry erase markers can be used to write the punctuation marks, but my favorite is to put magnets on the back and sort them on cookie sheets. That is why I included the headers.
