Lewis's Chinese writings at 5 year old

Lewis Chinese characters writings at only 5 years old. Grandpa mighty proud of him. Below is a photo of his writings (click photo to enlarge):

I do not have formal Chinese (Mandarin) education, but I think what he wrote was:

1. Wo zhuo fei ji chi liew xing (I got on an aeroplane to go touring)

2. Ma lu shang you yi liang che (On the road there is a car)

3. Chuan zhai hai sang piao lai piao che (The ship on the sea float here float there)

Do correct me if I am wrong.
