For example, for the first poster, a pair might say:

It means there is trash in the park． There are papers on the ground． We can help clean up the park by picking up papers and trash． We can make the park clean．

After the students have finished all the items, ask the students to add some other ways they can help people． Get them to write the ways down in the box below the picture．

Play the I'd like to statements on the recording to
