Fine Motor Skills

Some of our students' fine motor skills slow them down when they write.  Our learning specialist suggested we try using these stamps with these students to see if it helps.  This student was able to finish "I wd to the store" during the writing workshop time, but I was with him the whole time.  We'll see what happens when he works on his own.  The specialist also suggested putting the stamps on everyone's table so not to isolate anyone...  Any other fine motor ideas for in the classroom?
