This game is a fun way for students to practice adding and subtracting integers, writing combinations, and turning fractions to decimals and percents. Students will roll two different colored dice (one representing a positive integer and one representing a negative integer) and find the sum. Next, students will cross off two numbers in the table with that same sum (example: if the sum of the two dice is 3, students can cross off 5 and -2, 4 and -1, or 3 and 0). The student who is not rolling should make sure their partner is adding the integers correctly. The student will keep rolling until they can’t cross off any numbers in the table with the sum that was rolled. Next, the student calculates their total by adding the numbers that were not crossed off (use absolute value for negative values left over) and then it becomes the next person’s turn. The goal of the game is to have the lowest score at the end of the round. Give your students the opportunity to collaborate, have fun, and make meaning of important foundational level math standards!
