Greet students and start showing them pictures of national holidays in the USA (either on computer or printed out). Have students guess what holiday it is/try to elicit. Most students might not know. i.e.- This holiday is Independence Day. It is celebrated ON July 4th. It is celebrated AT the park. We celebrate it because the USA gained Independence from the British IN 1776. This holiday is Thanksgiving. It is celebrated ON the third Thursday IN November. It is generally celebrated AT dinner time. We make lots of of food and eat turkey. Next elicit student responses about holidays in their own country. Ask them briefly to explain some using the prepositions, preferably. Write them on the board. Ask them if one must work that day or not.

Show students the EXAMPLE POSTER of Olive Day. READ it to them. ELICIT from students what it is that they will do. Explain what they will do if they do not understand. Make use of ICQ's Pass out materials. WRITE on the board: Must use prepositions: IN, ON, AT Must use: ordinal numbers, months, dates, etc. What day is it celebrated on? Where is it celebrated? What time is it celebrated? Why is it celebrated? Have students work alone on this. Each student will have 10-15 minutes to prepare their posters. The teacher will monitor. May have students work in groups, depending on students' ability and situation/class size.

Students will take turns presenting their national holidays to the class. Teacher and students will be listening for correct prepositions, ordinal numbers, months, dates, etc. NOTE: This activity may change according to the class size or students' ability to perform. May have students work in groups of 2-3 and then do a gallery walk of the national holidays if needed.
