In Multiples of Ten Addition War students learn to add multiples of ten with 2 digit numbers and compare sums. Students flip over their cards at the same time and add the multiples of ten with a 2 digit number. The player with the largest sum wins all cards. War happens when there are equivalent answers. The student who has the most cards at the end of the game wins! This game is ideal for partners, small groups and math centers. There are a total of 64 multiples of ten addition cards. In addition, there is an answer sheet and an answer key to play as Scoot, Read the Room or use as Task Cards.
