Math Games
With Jane and Joanne

Double Trouble



Grades 3 and up


  • adding and subtracting to 18
  • adding double digits


  • 2 players of equal skill


  • playing cards Ace (=1) through 9
  • a die


Place the deck of cards in the middle of the playing area. One of the players turns over a card and the players double the number (value) of the card to arrive at the sum.

Next, the die is rolled. Players must subtract the smaller number (between the card and die) from the larger number. The first player to say aloud the correct answer collects the card.

  • A player chooses a 4 from the deck of cards. The players double that (4 + 4 = 8) in their heads.
  • A player rolls a 6 on the die. The players subtract 6 from the 8 for a total of 2.
In the event of a tie (players give the same answer at the same time), the card is left on the table and play resumes until one player says the correct answer before the other. That player will take all of the accumulated cards on the table.

Play continues until the common pile is gone. The player with the most cards is the winner.
