Give each student one of the small cards after practicing days of the week and subjects.
Make pairs and greet each other and share information 'English on Monday' 'thank you, math is on Thursday'.
Then switch cards and make a new pair.
After doing this for a certain amount of time have the students sit down and give out the worksheet. Check their memory and see if they can fill in the blanks. After that check the answers.
Optionally collect the cards first to make it more difficult or let nearby students help each other.
