African elephants, chimpanzees, kangaroos, manatees, cheetahs, polar bears． If necessary, read the words and ask students to repeat them again． Then have students read the words by themselves．
Make sure students can read the words correctly and fluently．
Read the directions to the class． Point to the list of words in the box． Read the words and let students repeat them． Then get different students to explain what they think each word means in their own words． For example, A gentle animal is quiet and not dangerous． A fury animal is covered with soft hair． Ask some students to explain any words students may not understand．
An enormous animal is very great．
