A teacher-facilitated activity that teaches students to add fractions with like denominators.
While Alan and Ada Ant build sandcastles, students develop a conceptual understanding of fraction addition. They use strip diagrams, find common denominators, and adjust partitioning to create fractions with a common denominator.

This activity includes clear and concise teacher directions and Think Aloud questions, a detailed answer key, and conversation starters that give students what they need to have meaningful academic discussions.
A companion activity, The Big Bug Build, deals primarily with subtraction.
