Give the class a summary of Toby's experience. Rewrite it as a news article.
Toby Brown went to Thailand with his family when a tsunami struck. He was pushed under the water, but he and his brother survived by staying on top of the water and floating inside the entrance to the hotel and climbing up the stairs to the top of the building. They found their parents at the hospital. Their mother had a broken wrist and their dad was with her. They were very lucky.
