While-task procedure
1 show a photo with traffic lights in
ask : what are they?
Can you see the green man?
Can you cross the road now?
A sentence flies in: Cross the road. Walk quickly.
The whole class read the sentence.
Invite some individual students to read.
ask: Why do we need to walk quickly?
Because the green man will soon change into the red man. (help them to answer)
2 show a photo with the red man in
ask: can you cross the road now?
a sentence flies in: Don’t cross! Wait on the pavement!
(do the same as the above one, ask them to read)
3 show a to students
ask: what does it mean? It means can or can’t, do or don’t? Then add a bus into it, encourage them to guess what it means.
Show a students may know it means the opposite to the former one, it means can/do.
Then put letter “p” into it, ask them what P stands for here, what does this sign mean.
