These cards are large. They are meant to be printed on white paper to assist with low vision students. There is 1 number or 1 number representation per card. Each each card is outlined in dots for a cutting guide, if you are using these for matching. Additionally, each card has a dotted line down the middle, so they can be folded in half and used as flash cards. GREAT for time delay. Each card is 6 inches tall, with numbers or number representation being large.
