The eleventh is a big number that comes after ten when we count. It is made up of one ten and one more thing. So, if you counted ten fingers on your two hands and then added one more finger, that would make eleven.
When we are counting, we start with one, then two, then three, all the way up to ten. Then, we add one more to get to eleven. Eleven is a special number because it is the first number that is made up of more than one digit.
Sometimes we see the number eleven written as 11. This is just a fancy way of writing it so that it doesn't take up as much space.
We use the number eleven to talk about things that come in groups of 11. For example, if you have 11 marbles or 11 candy pieces, you have 11 of them in total.
In some sports, like soccer or football, players on a team wear a number on their jersey so that fans can easily identify them. Sometimes, a player will wear the number 11. This means they are the 11th player on the team and they are usually a forward or scorer.
So, to summarize, eleven is a number that comes after ten and is made up of one ten and one more thing. It's used to talk about groups of 11 things and sometimes in sports, players wear the number 11.
