Snap Two It -- Addition



Grade 2 - 3 and up


  • place value -- 2-digit numbers
  • adding 1-digit and 2-digit numbers


  • 2


  • playing cards Ace (=1) through 9


Divide the cards evenly between the two players. Each player turns over two cards and uses them to create a 2-digit number. The player says aloud his or her number.

Each player turns over a third card and adds the number on it to their 2-digit number.

  • Player 1 draws a 9 and a 1; he says aloud his number, 91.
  • Player 2 draws an 8 and a 3; she says aloud her number, 83.
  • Player 1 draws a 7 and adds that number to his 2-digit number (91) for a total of 98.
  • Player 2 draws a 4 and adds that number to her 2-digit number (83) for a total of 87.
The player with the highest number wins all of the cards. Play continues until one player collects all of the cards in the deck.


For advanced Grade 3 students and above: move up to 3-digit numbers. Add 2-digit numbers to them. Use playing cards Ace (=1) through 4 for addition problems that require no regrouping; use cards Ace (=1) through 9 for regrouping.

  • Player 1 draws three cards -- a 2, an 8, and a 6 -- and uses them to create the 3-digit number 862.
  • Player 1 draws two more cards -- a 4 and a 3 -- and uses them to create the 2-digit number 43.
  • Player 1 adds the two numbers created (862 + 43) for a total of 905.
