Let’s ReviewExtension ActivitiesRoll and Race

Play with a partner

Materials Needed: 2 pair of dice, number line strips(copied or drawn number lines of the same length)and a writing tool.

To Play: Each player rolls their dice. The greater number is the denominator and the least number is the numerator.

Plot the fraction on your number line.

Score a point for the greatest fraction each round. Both score if they are equivalent. At the end of 10 rounds each player gets 5 points for each equivalent fraction pair.
