This is a Word-Build-Write mat we use in our class. The students pick a sight word and put the card in the "word" section of their mat. Then they build the sight word with magnetic letters in the "build" section. Finally they write the sight word on the lined section of the mat.
The file includes the Word-Build-Write mat as well at the kindergarten sight word cards we use! (I have 2 sets of cards, one set is typed using a handwriting font so the students know how to properly write the words!)
