Read the yeti's diary. Find past simple irregular forms. Yesterday I heard noises in my home. There were some strange creatures there! They had short arms and legs and horrible hair. They were very ugly! I was hungry, but I didn't eat them. I went behind a tree and hid. Then I watched them. They found my food. They took it and ate it. Then they made a fire and drank some water. They saw one of my footprints and looked at it for a long time. After two hours they left... What were they? It's a mystery! ​
