When I was four, I used to believe that I could only count to 10. Then my mom gave me 13 balls and asked me to tell her what the number was. I saw that they were a lot, so I suspected 10 because it was the highest. So I said 10, but it was wrong, and I didn't understand. I counted them. I stopped at 10. "Mum! There are 10 balls but 3 extra!" Mom said, "no, there are no extras, this number is called 13." then she taught me to count up to 20. At six, I also thought that 20 was the highest number, but I heard people saying things like 23 (which I now understood, from being taught adding, was 20 plus 3) and remembered what my Mom told me. So I thought, "hey, there's such thing as 20 + 3!" it got kind of confusing from there.
