"What are fractions composed of?" is the essential question of a lesson designed to enhance understanding and strengthen the foundation of adding fractions. Mathematicians start by discussing what makes an equation true or false, then use manipulatives to prove or disprove decomposed fraction problems. Following a discussion, scholars solve an addition problem consisting of fractions with a common denominator, then summarize their overall understanding of the concept.
