4. A game to play -
Multiplication War with Negatives: played with Skipbo cards (or regular cards 1-10) similar to “War”. Red and Orange cards are NEGATIVE, and black/blue cards are POSITIVE. Deal out all cards to both players. Each player turns over 2 cards, face up, multiply. The player with the PRODUCT closest to zero (or greatest value) gets all the cards. The player with the most cards wins.
