Addition 4
With 21 problems, this is the most demanding of the fraction addition quizzes, leaning heavily on fifths alongside halves and thirds. You will tackle additions like 2/5 + 3/5 and 3/5 + 2/3, some landing on a clean whole number and others on a mixed number you will need to simplify. Recommended for students who are already comfortable adding fractions with unlike denominators. A satisfying detail: a few problems, such as 2/5 + 3/5, add up to exactly 1, a nice reminder that fractions sharing a denominator are the easiest kind to combine.
