Divide the class in half. Assign each student a partner in the opposite group. Each student knows who their partner is, but the two groups sit separated so partners can 愒 communicate in stage one.
Give all of group A a list like this:
My friend can/can 愒 ride a bicycle.
My friend can/can 愒 sing an English song.
My friend can/can 愒 play the piano.
etc etc ... about 6 to 8 of these should be fine.
Give a similar list to group B, but with a different set of sentences.
The idea is that each student looks at their partner and tries to GUESS if they can or can 愒 do each of the things in the list. They delete 惡an � or 惡an 愒 appropriately.
In stage two, students sit together with their partners (face to face) and ask questions to find out how many correct guesses they 扉e made.
So ...
Can you ride a bicycle?
Can you sing an English song?
As a feedback, you can invite students to make a sentence using this structure ...
"_______ can ________ but she can 愒 _______."
eg "Kimiko can play the piano, but she can 愒 juggle."
Hope this helps and hope I 扉e expained it clearly.
