0
0

A teacher-faciliated problem solving introduction to fraction addition.

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.

5 problems include fractions with different denominators.

Use with the whole class to introduce or practice fraction addition or during tutoring or intervention.

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, Castles Made of Sand – The Competition, deals primarily with subtraction.
