This activity takes some planning on the teachers part but it is WELL worth it! First, let me explain what the teacher will need to do as prep.
dish washing detergent
Print the playing cards on the cardstock
Laminate the playing cards
Cut out the playing cards
Mix the "scratch off" paint. (1 part liquid dish detergent and 2 parts acrylic paint)
Paint over the answer box.
Allow to dry (20-30 minutes)
Once the cards have been printed and laminated, you will be able to reuse these! You will only have to repaint for the next use.
I created two versions of the game and my students loved both of them. I had several cards left over so I made an early bird station with the extra cards.
