personal earthquake bag?
S2: If we have to collect things we need
for five days, the most important
things will be the bottle of water, candles, money and personal washing things. That makes four, do you agree?S1: Yes, they sound good choices. I also think we need a torch, a mobile phone and a blanket. Another one?
S2: OK. But now we have difficulties. I would like food and sweets. We’ll really need food if we’re to be on our own for five days before rescue comes.
S1: No, I don’t agree. Food and sweets is a good idea but the medicine would also be very useful.S2: I agree. So we have to choose whether to take the food and sweets and the medicine to make our eight items.
S1: OK. Now, let’s make the list: water, candles, money and personal washing things, food and sweets, a torch, mobile phone and blanket. If we want to add the medicine as well, what can we remove?S2: Well, the candles and the torch do seem to be the same. Why don’t we remove the candles (in case we don’t have matches) and replace them with the medicine?
S1: Yes. That seems to solve the problem. OK. Let’s put the medicine in and take the candles out. Now our list is complete. Let’s tell the class our ideas and see if they have the same ideas…
