Kindergarten students will enjoy the excitement of this addition game. Call two volunteers to stand back-to-back in the front of the class. Each student will need to place a card from a deck of playing cards with the face cards removed on her forehead. At the signal, the two dueling students walk three paces forward and turn to face the class. The class adds together the two numbers on the cards and tells the students the sum. The dueling students turn to see the other's number and calculates what their own number is. The first student to correctly say her number stays in front of the class to duel with a new competitor.
Inflate a beach ball and write numbers all over the ball with a permanent marker. Students stand in a circle to begin this game. Toss the ball to one student. He must look at the numbers his hands land on, add the digits together and call out the sum. If the answer is correct, he tosses the ball to another student. If the answer is incorrect, he will need assistance to find the correct answer.
Remove the face cards from a deck of playing cards. The class must be divided into working partnerships. Students deal the cards between themselves and keep their pile upside-down. To begin the game, each student turns over two cards and adds the numbers together. The student with the larger sum keeps all four cards. If the two sums are equal, each student turns over two more cards to be added. The student with the highest of these two sums keeps all eight cards. Play continues until one student holds all of the cards.
Photocopy a three-by-three grid square for each student. The squares should be large enough for kindergarten students to easily write a number inside. Roll a die and call out the number to the class. Students must decide where in the top six boxes they would like to write that number. The die is rolled five more times until all six boxes on the top two rows of the grid square are filled. Allow students time to add each column and write the sum in the bottom boxes. The largest sum found is the winner.
