I've used clip art from www.mycutegraphics.com to create these mats. Laminate and give students play dough to form into the letters of the words.
Words included are: turkey, harvest, pie, family friends, Pilgrims, corn, feast and Native Americans.
Each word is on its own page with a coordinating image. These can also be used as a themed word wall, coloring sheets, and other word activities.
Let me know if there is anything else you would like in this theme and I'll see what I can do.
