Learning to read - sister's bus (AVI-Start)

Sister is going on a trip with her bus. Will Piet fit in the crowded bus? And who else will they meet along the way? Funny story about a fun trip at AVI Start. Every beginning reader in group 3/year 1 wants to show how well he can read. How much fun is it to show that with this recognizable story full of short words and simple sentences? That's a great way to make some reading miles.

I'm fed up, says sister.
I'm leaving.
And what about me? says Piet.
You can come along, says sister.
But ... will Piet fit in the bus?
Or is sister's bus already full?
