Going to

Start by saying that all of us (the class) are friends with Paul (or any name you like), and that we are all going to bring him a gift/present. Explain that it´s a memory game and you have to remember what everyone is going to bring and continue until someone makes a mistake.
Example:
(First person) I´m going to Paul's party and I´m going to give him a t-shirt...
(second person) Í´m going to Paul´s party and I´m going to give him a t-shirt and a book...
So on and so on.
This can work for any level but especially basic. To make it harder you can make them adjectives and add rules such as all the nouns can only start with `s´.
