Teachers and students will enjoy these handmade "Giant Playing Cards." Teachers can use the "Giant Playing Cards" as flash cards for adding, subtracting, multiplying, and dividing. (I count aces as "11" and face cards as "12.") Use a color printer with stock paper and you are ready to go. Better yet, make the "Giant Playing Cards" more permanent by laminating them. I realize now I am a little OCD by completing this task. LOL!
