Topic Introduction & Real-World Context:

Numbers are indispensable for telling time, asking prices, shopping at markets, counting objects, and stating your age. French numbers from 0 to 100 follow a logical system with unique patterns between 70 and 99.

What You Will Master in This Lesson (NaCCA Objectives):

Count and write numbers from 0 to 100 in French.

Master complex number formations from 70 to 99 (soixante-dix, quatre-vingts, quatre-vingt-dix).

Ask and state age using the verb AVOIR: 'Quel âge as-tu ?' → 'J'ai douze ans.'

Perform simple arithmetic operations (plus, moins, fois, égale).

1. Les Nombres de 70 à 100 (Les Formations Spéciales)

While 20 to 60 follow standard patterns (vingt, trente, quarante, cinquante, soixante), 70 to 99 use base-20 and compound math:

Les 70: '60 + 10' → 70 = soixante-dix, 71 = soixante et onze, 72 = soixante-douze, 79 = soixante-dix-neuf.

Les 80: '4 × 20' → 80 = quatre-vingts (takes an 's' on vingt when alone). 81 = quatre-vingt-un (loses the 's' and no 'et' !), 85 = quatre-vingt-cinq.

Les 90: '4 × 20 + 10' → 90 = quatre-vingt-dix, 91 = quatre-vingt-onze, 95 = quatre-vingt-quinze, 99 = quatre-vingt-dix-neuf.

100: Cent.

Key Takeaway: Remember: 80 has an 's' (quatre-vingts), but 81 drops the 's' (quatre-vingt-un).

Real-World Application: A bus fare of 75 CFA is pronounced 'soixante-quinze francs CFA'.

2. Demander et Exprimer l'Âge (Verb AVOIR)

In French, one HAS years rather than BEING years:

Question: 'Quel âge as-tu ?' (How old are you? - informal) / 'Quel âge avez-vous ?' (formal).

Structure de réponse: Sujet + forme du verbe AVOIR + nombre + 'ans'.

Exemple: 'J'ai treize ans.' (I am 13 years old). 'Kofi a quatorze ans.'

Attention BECE: Never use the verb 'être' for age (e.g. 'Je suis 13 ans' is incorrect).

Key Takeaway: Always use AVOIR for age in French: J'ai... ans.

Common Mistakes Students Make in BECE Examinations:

⚠️Using 'être' instead of 'avoir' for age ('Je suis douze ans' instead of 'J'ai douze ans').

⚠️Writing 'soixante et dix' instead of 'soixante-dix'.

⚠️Adding 'et' to 81 ('quatre-vingt et un' is wrong; write 'quatre-vingt-un').

Teacher's BECE Exam Pro-Tips:

⭐Always write 'ans' at the end when stating age ('J'ai 12 ans', not just 'J'ai 12').

⭐Practice spelling tricky numbers: seize (16), treize (13), cinquante (50), soixante (60).

Quick Revision Summary Checklist:

Can count from 0 to 100 in French.

Can write 75 (soixante-quinze), 82 (quatre-vingt-deux), and 94 (quatre-vingt-quatorze).

Can state my age using 'J'ai ... ans'.

Can perform simple additions and subtractions in French.

Step-by-Step Worked Examples (2)

Real BECE exam-standard problems with complete solution steps

Example 1: Exprimer l'Âge avec le Verbe AVOIR

Problem StatementTranslate to French: 'Akosua is 13 years old and her brother is 15 years old.'

Step-by-Step Solution:

Step 1: Identify the subject and verb: Akosua has 13 years (verb avoir: a).

Step 2: Translate 13: 'treize'. Add 'ans': 'Akosua a treize ans.'

Step 3: Translate 'her brother': 'son frère'. Has (a) 15 (quinze) years (ans).

Step 4: Combine: 'Akosua a treize ans et son frère a quinze ans.'

💡

Key Takeaway / Exam Rule: Always use the verb AVOIR followed by the number and 'ans' to state age in French.

Example 2: Calculer en Français (Simple Math Operations)

Problem StatementWrite out in full French words: '25 + 15 = 40' and '80 - 10 = 70'.

Step-by-Step Solution:

Step 1: '25' = vingt-cinq; '+' = plus; '15' = quinze; '=' = égale; '40' = quarante.

Result 1: 'Vingt-cinq plus quinze égale quarante.'

Step 2: '80' = quatre-vingts; '-' = moins; '10' = dix; '70' = soixante-dix.

Result 2: 'Quatre-vingts moins dix égale soixante-dix.'

💡

Key Takeaway / Exam Rule: Use 'plus', 'moins', and 'égale' to perform and state calculations in French.
