French: Problème de maths addition et soustraire grade 5
Problèmes de mathématiques, Volume 1 opens with a filled addition table to 9 + 9 and step-by-step column lessons — addition sans retenue and avec retenue, then soustraction sans emprunt, avec emprunt, and avec emprunt et plusieurs zéros — before turning to thirty-three French word-problem sets. Scenarios run from Le Potlatch and Les cartes de Pokemon through Visiteurs au musée, Le magasin des bonbons géants, La traite des fourrures and Les explorations, and they lean on price lists, a distance map, and tables with missing totals. Numbers reach six digits and decimals to hundredths, and nearly every question closes with Montre ton travail. Worked Corrigé sections follow the scenarios; some keys span several pages.
