ELEMENTARY LATIN NUMBERS ROMAN NUMERALS Salvete! These word wall cards are great for creating an instant introduction to Latin numbers and Roman Numerals 1-20. I really like to have key vocabulary displayed in a particular area - I find it gives the learning environment a real language 'feel' and 'look', keeping the language alive every day - and of course the word wall cards are useful during the introduction phase, and we also use them for developing language skills and awareness in general.
