This game makes factors and multiples so much fun! It is played like traditional UNO, but instead of matching cards of the same number, students match the number on the top card in the discard pile to a factor or multiple of that number. Cards of the same color can also be matched. Higher numbers (up to 100) are included so students really have to think and go beyond just basic recall. Encourage students to use a dry erase board or scratch paper to divide/multiply if they're not sure whether they have a factor or multiple of the number on the top of the stack.
Two versions of the cards are included, one with full color cards and one that uses less ink. :) Please let me know if you have any questions or suggestions. Thanks!
