Swimming is very important because you might drown. At my school we learn how to swim at the back of our school.
I learnt how to float on my back. You have to put your arms out like a star fish and slowly bend down on your back. Next you just push your tummy up and you will float. I am good at doing arm strokes with a kicking board. I am not good at back strokes.
In conclusion, schools should have a pool so their students learn how to swim.
