A nice nursery rhyme (traditional British song for kids) to practise the numbers.

1, 2, 3, 4, 5
Once I caught a fish alive
6, 7, 8, 9, 10
Then I let him go again
Why did you let him go?
Because he bit my finger so!
Which finger did he bite?
This little finger on my right

A fish should be IT, not HE, but in children's stories animals are often treated as "people" (especially if they can speak) so they use HE/SHE. Anyway, this song is usually sang with IT, not HE, but on this video they say IT.
