PILES (Fraction Equivalence): Sorting Activity for Math Talk (Grades 3-5)

Engage students in mathematical reasoning with this sorting activity for equivalent fractions. Students start by identifying anchor cards, then sort the remaining cards into piles matching the anchors. Piles may have different numbers of cards as students recognize equivalent fractions with both like and unlike denominators. This resource encourages math talk as students defend their reasoning for creating piles. Use it independently, in small groups, or whole class. With 10 puzzles from basic to advanced, it's great for grades 3-5 to reinforce fraction concepts, prepare for standardized testing, and develop critical thinking skills. The resource includes answer keys and a sample lesson plan aligned to Common Core math standards. This hands-on, engaging activity uncovers misconceptions about equivalence and the equal sign while aligned to key math practices.
