Fraction Pizza Party Warm-Up
Look at these two pizzas Pizza A: 3 out of 4 slices eaten Pizza B: 3 out of 6 slices eaten Which pizza has more left to eat? Explain your thinking to a partner

Comparing Fractions Rules
{"left":"Same Numerator: Compare denominators - smaller denominator means bigger pieces\nSame Denominator: Compare numerators - bigger numerator means more pieces","right":"3/4 vs 3/6: Same numerator (3), but 4 < 6, so 3/4 > 3/6\n2/5 vs 4/5: Same denominator (5), and 2 < 4, so 2/5 < 4/5"}
