- Tell them that each red card symbolizes a negative integer, and each black card symbolizes a positive integer.
- For round 1, ask both players to turn over a card at the same time and show it face up on the table. Whoever announces the the correct product, (answer), aloud first, wins both cards. If there’s a tie, both players can keep their cards.
