Give two fractions a matching bottom number, then add or subtract the tops — the common denominator is set for you; dial the numerator of the answer.
The common denominator is already provided, so children can focus on the core step: rewriting two fractions with the same bottom number and then adding or subtracting the numerators to reach the answer. This focused approach builds confidence with common denominators and fraction addition or subtraction before the harder step of finding the denominator independently. Best for Grades 4–6, or anyone at the start of fraction arithmetic.
