Unit 2　Healthy eating

Period 7　Revision: Summing up and learning tip

整体设计

教材分析

This is the last teaching period of this unit, so the emphasis should be placed on going over and summarizing what has been learned in this unit. It includes the following parts: Summing Up, Learning Tip, assessment and consolidation exercises.

Summing Up summarizes the whole contents of this unit from the aspects of topics, vocabulary and grammar. The teacher can first use this part to let students sum up what they have learned and then explain what students couldn’t understand very well in this unit. An experienced teacher should design some additional exercises for students to do in order that they can learn to use and grasp all the contents.

Learning Tip encourages students to look at the side of the packet or tin when they buy food in packet or tin. This will help them not only know how much sugar, fat, vitamin, protein, and fiber there is in their food but also learn more words and expressions connected with food. They can use this information to help them have a healthy diet as well as increase their vocabulary. So make sure that students have a try.

In this period, the teacher can also provide more practices to consolidate what students have learned in this unit.

Finally, ask students to finish Checking yourself on Page 54 in the Workbook. This part aims at encouraging students to make a self-assessment after they finish learning this unit. It is very important to improve their learning. Of course, a testing assessment is also needed.

3. Write a sign to advertise the benefits of your drink or food and invite others to have a try.

4. Share your recipe with your group. Then decide which of the group recipes sounds the most delicious and healthiest.

Here are some steps for you to follow:

1. Do some research among the class to see which drink or food are the most popular.

2. If you design a new drink, make sure it is healthy(no added sugar)and includes real, fresh fruit(fiber). If you are going to design a food(e. g. a roll), then make sure it has a fresh, healthy filling.

3. Let the group test it and adjust the flavor or taste.

4. Prepare to test it on the class. Ask for comments to improve it.

5. Finally make the poster for others to make it.

Sample poster:

The Fruit Crush Special

Come and try it here! Once tasted, you will want to make your own version. Just follow these simple instructions and a fruit crush special will be yours!

You need:

1 banana, 1/2 small watermelon, grapes, 1 apple, 1/2 kg strawberries, melon, ice

To get the best flavor you ought to cut the fruit up into small pieces. Then you have to mix the ingredients up together in a blender to make the drink smooth. Add mineral water as required. You can include other fruit as needed. When you serve the drink, you should first place the ice at the bottom of the glass before you pour the drink on top.

Drink and enjoy!
