⏱ 5 minutes Β· πŸ“š CELTA-informed Β· 🎯 A1 Cambridge level

πŸ“– From the teacher’s desk: At Merivale in Sydney, counting was everything β€” 16 covers on table 4, 3 bottles of Bollinger for table 12! Numbers in English felt natural to me because I used them hundreds of times a day. Children learn numbers fastest when they count real, tangible things around them.

🎯 By the end of this lesson, you can: count from 1 to 20 in English and use numbers in simple sentences.
