A Pedagogical Sequence for Introducing Tasks

I'll use the following six-step instructional sequence to tell you how I am going to work the unit "Giving Directions" with 5° grade of Primary School.

Step 1	Look at pictures of different cities. What shops can you identify? What shops are there in your town? Identify the names and match them with the pictures.
Step 2	Read and listen to a conversation between two people asking and giving directions. Practice the conversation.
Step 3	Listen to different dialogues and match the conversations to the maps.
Step 4	Listen to the dialogues again and complete the written conversation with the missing words or phrases.
Step 5	Pair work. The teacher will give the students a map and they will have to ask and give directions according to the map.
Step 6	Final task: students have to make a mock up of a town and bring their toys to class. With the toys, they will have to create dialogues asking, giving and following directions.

Halliday's three macrofunctions of language

When I was teaching 2° grade some years ago, we did the following activity, which can be analized according to the macrofunctions of language described by Hallyday.
After studying the toys and numbers up to 20, I asked the students to bring their toys to class. We designed a toy shop in the classroom and put prices to the toys. Some students were the sales assistants and others the customers.
Students loved the activity and it showed how much they had learnt!
