Have some math fun in your class!
Break the class into two teams. Pick a captain for each team. Hand each captain one of the sets of cards, either Set A or Set B. The team captain can have each team member pick a card at random from the set without looking. Once both teams have their cards, instruct each team to arrange the cards from least to greatest or from greatest to least whichever you determine. From least to greatest is generally easier because it is arranged like a number line. From greatest to least adds that extra challenge. The first team to have all of the cards in the correct order wins!
