🔢 One, Two, Three!

⏱ 5 minutes · 📚 CELTA-informed · 🎯 Cambridge A1

📖 From the teacher’s desk: Working as a sommelier in Sydney, I used numbers constantly — “Table 12, two glasses of Shiraz, four of Riesling.” My young son now loves counting everything at home in La Réunion: mangoes, shells on the beach, even the geckos on our wall! Numbers are everywhere.

🎯 By the end of this lesson, you can: say numbers 1–20 in English and count objects around you.
