Step 1 Revision
1 Check the homework exercises.
2 Do the following exercise.
What is important about these dates or figures?
1524 $24 125,0001858 1892 15,000,000
2,000,000 1900 193 1 73 50,000 24 hours
Step 2 Presentation
Find out how much the Ss know about the central plains of America. Write the title of the text on the Bb and ask Ss to tell you anything they know. Put any useful notes and key words that arise out of this discussion on the Bb. Teach the new word bison, using the picture in the book. Then SB Page 3, Part 1. Get Ss to talk about the picture and describe what they can see.
Step 3 Reading for general understanding
Read aloud the two questions. Then tell the Ss to read the passage quickly and write down the answers to the questions. Allow the Ss enough time to read the text, write down the answers and compare them in pairs. (1 The settlers killed them, forced them to leave their hunting grounds, broke agreements which they had made, forced them onto poor land, and killed most of the bison on which Native Americans had relied for food. 2 The killing of large numbers of bison changed the whole wildlife chain on the plains.)
Step 4 Reading
Wb Lesson 50, Ex. 1. Go through the exercise and make sure the Ss know what to do. Let them read the whole passage carefully and answer the questions, working in pairs or small groups. Check the answers with the whole class. This is a goodtime to deal with any language problems. See if the Ss can guess the meaning of westwards, afterwards, widespread, rot, etc.
Notes：
a bison： This is a large mammal, related to cattle.The scientific name is bison, and the common name is buffalo, as used in the name Buffalo Bill. The term bison is used to distinguish it from the domesticated water-buffalo found in North Africa and Asia, and the wild African buffalo, which is dangerous.
b across the country： Point out that many prepositions like across can be used to indicate place as well as motion.
c Now that they could ride horses = Because they could now ride horses
d a shoulder-height： height from the ground to the shoulder. This is the common way of measuring many large mammals, e.g. horses, cattle, deer.
e When they objected = Whenever they objected
