It is easiest to cut up the game cards if you have access to a paper cutter. Some tutors cut all the cards out in a session or two. It's a great activity to do while watching TV! Others cut out the cards as they prep for the next lesson. Once the cards are cut out you can use them forever.
The cards do not need to be laminated. I have my students wash their hands before we start a tutoring session. That way all of my materials, including the game cards, stay nice and clean. I have used my cards for 10 years and they are in great shape!!
