Video

You have seen today how numbers help us in everyday life. Can you imagine how we could work things out without using numbers? This video shows us an Aboriginal tribe which only has the word for “one” and does not use any other words for numbers! However, there was a study published in 2008 that showed that aboriginal children can count without words for numbers!
