Adding fractions with the same denominator is simple, but what happens when the denominators don’t match? Students often fall into the trap of adding numerators and denominators straight across — a classic misconception that leads to incorrect answers.
To add fractions with unlike denominators, fractions must first “speak the same language” by converting them using a Least Common Denominator (LCD).
In this post, we’re sharing a step-by-step strategy for finding common denominators, along with a free downloadable Indiana Jones-style adventure worksheet complete with an ancient map, journal word problems, and a complete teacher answer key!
Before you can add two fractions together, their slices must be the exact same size. Follow these three archaeological steps to unlock any fraction puzzle:
