These cards can be printed on cardstock, laminated, and placed on a metal ring to use for quick assessment. There are 8 pages included. A, B, C, D, Yes, No, True, False. I would suggest printing the ABC on green (Letter A), yellow (B), and red (C) cardstock. The back of those cards can also represent "I got it" (green), "I'm not too sure" (yellow), "I need help" (red).
