Objectives By the end of the lesson students will be able to: - Interpret and compare data described in chart/ graph/ table form and write a report of data analysis. - Understand a chart and know how to describe a chart. II. Material Textbook, handout, sub-board and pictures III. Procedure Time Teacher’s activities Student’s activities 3’ I.Warm-up: -gives students some pictures about the energy and ask them these questions: + What do these pictures talk about? -explains more details if students can not guess. -corrects students ‘ answers - Look at the pictures and give comments + The first picture is about wasting water power. + The second picture is about exploiting the water power to make the electricity. + The third picture is 10’ III.Prepare students to write  Vocabulary: _gives some new words to students _explains by pictures or others way(nomally directly because newwords are quite difficult to explain by synonym) Task 1: -asks students to remind how to interpret data in a table/ graph/ chart. -gets students to work in pairs to study the 2000 charts on page 130 by asking questions like: + What is the topic of the chart? Does it describe the past, the present, or the future? + Which made up the largest amount of consumption : petroleum, coal, or nuclear and hydroelectricity? + Which consumption ranked the second? + Which made up the smallest amount of consumption? -gets students to do task1: -gives notes:( delivers handouts) 1. To describe the graph/ chart /a about how to save the water power  Vocabulary: - consumption (n) sự tiêu thụ - hydroelectricity (n) thủy điện Task1: - To understand a chart, it is important to understand its topic firstly. - Pay attention to the time reported in it. Is it the past, the present, or the future? - Work in pairs and discuss: + Its topic is about the energy consumption in Highland in 2000. + Petroleum made up the largest amount of this figure. + The second is the consumption of coal. + The smallest amount of energy consumption is nuclear and hydroelectricity. - Do task1: 1. The total energy consumption was 117 million tons.( sum up coal, nuclear & hydroelectricity and 30’ (10’) table we often have two parts: + Introduction: - answer for the question “ What is graph about? The date, location. We have some phrase such as: the chart shows/ describes/presents…. Ex: The chart shows the energy consumption in Highland in 2005. -answer for the question “What is being described in the graph?”. Some structures such as: As can be seen from the chart…or it can be seen in the chart… Ex: As can be seen in the chart that the total energy consumption was 170 million tons. + Describing the chart in detail: decide on the most clear and logical order to present the material( from the largest to the smallest ). We have some expression like: make up the largest/ smallest percentage/ proportion ; this is followed by…,or this ranks first/ second… Ex: Nuclear and hydroelectricity made up the largest amount of this figure( 75 million tons). This was followed by the consumption of petroleum ( 50 million tons). Coal made up a slightly smaller proportion with 45 million tons. 2. Verb tenses: When the chart shows the present situation, use the present simple tense. When it shows the past events, use the past simple tense. III.Writing  Task 2: Before writing ,teacher asks students some questions:to help students write easily: -What is the topic of the chart? - Which the consumption ranked the petroleum). 2. Coal ( look at the chart). 3. Smallest ( 20 million tons). - Notes(write on the notebook)  Task 2: Answer questions in short: - The energy consumption, in 2005. - Petroleum 20’ second? - Which made up the smallest amount of consumption? -Uses Game : jumbled words Game : jumbled words 1. 1.
