Difference Drop at Machu Picchu

Subtraction Strategies Adventure Pack

High in the cloud-covered peaks of Machu Picchu, the numbers are falling away.

Minuends are crumbling. Subtrahends are disappearing mid-step. Regrouping paths are broken, and differences are no longer landing correctly. Ari Raider has detected a disruption in the subtraction system and needs explorers to restore balance before the calculation terraces collapse.

In Difference Drop at Machu Picchu, students are dropped into a high-stakes math mission where precision matters. By learning how minuends and subtrahends interact, how regrouping strengthens subtraction accuracy, and how related facts and mental strategies support problem solving, explorers must rebuild the number pathways and secure the final difference.

This adventure blends foundational subtraction skills with story, exploration, and optional hands-on discovery.
