You can play a nice memory game with flashcards stuck on the walls around the room.
Start by drilling the flashcards as usual.
Next, ask your pupil to stick them around the room (give them some blu-tac) and say each activity as they stick up the flashcard.
Then ask your pupil to sit in the centre of the room. S/He should point at each card in turn and say the activity.
Next, you say the activities but in a different order. The pupil must point to the card as quickly as possible. (You can also give the pupil a magic wand to point with or ask them to make a gun shape with their fingers as they point, if you are comfortable with that.)
Go back to the previous step, where your pupil points at the cards in turn and says the phrase. Run through this once as normal, then ask your pupil to close their eyes and repeat the activity. They should point to where they remember the card being.
As a final step, your pupil should be able to sit with their eyes cosed and point to the correct card when you say a certain phrase.
Why not challenge yourself and swap roles? The pupil can say the phrase and you have to point (with your eyes closed) - the pupil will tell you if you have remembered the position of the card correctly or not.
