Writing Folder
I have found this is more apt to get used than a separate book of high frequency words. I encourage my students to use the vowel pictures when stretching out unknown words when they write. Just like the math folder, I use clear packing tape to "laminate" the entire thing. You could also open the folder and put it through your laminator (slow speed), then cut the pockets back open with a scissors. I haven't done it yet, but have thought about using some kind of velcro marker for students to track where they are in the writing process.
