Cette seconde séance confronte les élèves aux soustractions complexes avec de grands nombres (jusqu'à 100 000) et se concentre sur le redoutable piège des zéros intercalés (ex: 10 004 - 3 245).

Cette première séance permet d'élucider le mécanisme de la retenue dans la soustraction posée. Les élèves comparent les deux techniques (emprunt/cassage de la dizaine vs. glissement/addition constante) pour choisir celle qu'ils maîtrisent le mieux.

A hands-on, collaborative math project where students work in teams to design and budget for an ultimate classroom picnic, practicing multi-digit addition, subtraction, and critical decision-making.
