Period 2 A sample lesson plan for Learning about Language
(odal verbs: may/ might, can/ could, will/ would, shall/ should, must/ can’t)
Introduction
In this period students will be first helped by the teacher to discover and learn to use some useful words and expressions, and then to discover and learn to use the following useful structures: may/ might, can/ could, will/ would, shall/ should, must/ can’t. The following steps of teaching may be taken: Warming up，Learning about grammar and Closing down by doing a quiz.
Objectives
To help students learn about odal verbs
To help students discover and learn to use some useful words and expressions
To help students di scover and learn to use some useful structures
Procedures
1. Warming up by discovering useful words and expressions
Turn to page 4 and do exercises No. 1, 2 and 3. Check your answers against your classmates’.
2. Reading and finding
Turn to page 1 and read the text of FESTIVALS AND CELEBRATIONS. As you read, find o ut examples of may/ might, can/ could, will/ would, shall/ should, must/ can used in the sentences.
3. Doing exercises No. 1, 2 and 3 on page 5
Turn to page 5 and do the exercises No. 1, 2 and 3 in groups of four.

Next we go on to make a careful study of all the modal verbs.

You should pay attention.
(weak)
You out to pay attention.
