Ask Ss what do we call very old things? "antiques". Ask Ss what antiques people collect? " clothes, jewellery,furniture,etc". Focus Ss' attention on the picture of the old "clock". Write 500$ next to the clock. Elicit from Ss how can we ask about the price of something. Write the words "price, cost, worth, pay, afford, sell, buy and exchange". Check that Ss know the meaning of them all.

Focus Ss on the HOs. Tell them that they are antique collectors. Give them the photos with the paper of instructions. Tell Ss to read the instructions carefully. Tell them that they have five antiques they have to sell them, and they have to buy five things "jewellery, clothes, toys,etc" as written in their instructions. Focus Ss on the prices and tell them that they can change them. Ss can sell their stuff or they can exchange them with extra money. Tell them if they have collected their five antiques, they will get an extra 500$ at the end. Draw a table on the board with headings " $spent, to person, $ made, from person". Tell Ss to draw the same table and fill in it as they buy and sell to stop cheating and\or to keep record. Tell them that the person with the most money wins. Provide Ss with enough time to do the task. Ss work together as a whole class. monitor and help.

If you wrote down any mistakes or notes during monitoring while the speaking activity, write them up on the board and ask Ss to correct them. Put Ss in pairs and tell them to take turns to tell each other about what was their mistakes during the activity and what was their best buys. Ss share their ideas with the class.
