Equivalent Fractions Quiz
Take this 20-question equivalent fractions quiz to check whether your fourth or fifth grader has truly mastered the concept of fractions that look different but have the same value. Each problem asks for the missing numerator that makes two fractions equivalent — exactly the skill they'll need for adding fractions with unlike denominators next. Aim for 16 out of 20 or better; anything less and the underlying multiplication facts probably need more work first. Quizzes are best taken after a few days of practice, not as the first exposure to a topic.
