French: Problème de maths addition et soustraire grade 5

Add and subtract multi-digit whole numbers to six digits with the retenue and emprunt column methods modelled on pp. 12–13 and 17–21

Place sets of large numbers dans l'ordre croissant or décroissant and justify the placement by comparing the numbers (pp. 22, 32, 52)

Write the reasoning in French, responding to Montre ton travail, Explique and Explique ta pensée with a full answer sentence

Pages 5–21 work as a reference booklet: the scenarios from p. 22 onward assume the column layout and the French vocabulary (termes, somme, différence, retenue, emprunt) taught there.

Each Corrigé sits on the page directly behind its scenario, so pull the scenario pages separately when students should work without the solution in view.

Scenario headers all carry 5ième or 5ième année, which makes loose photocopied pages easy to sort back into order.

Multi-digit column addition and subtraction — students work totals such as 212 512 + 121 620 + 454 490 and differences such as 100 000 – 55 646 using the retenue and emprunt steps set out on pp. 12–13 and 17–21.

Comparing and ordering large numbers — students place figures like 54 001, 52 101 and 43 011 dans l'ordre décroissant and explain in French which season, city or collection is largest (pp. 22, 24, 32, 52).

Reading French mathematical instructions — students act on prompts including Montre ton travail, Explique ta pensée, ordre croissant and Combien de temps while solving entirely in French.
