I try to avoid describing it as games, as I've learned from experience that that also raises expectations. Usually, I tell children that we are going to do some different activities that help us understand how you learn best. Some things may be easy, and some may be hard. That's normal. Just do your best, and give everything a good try. You may ask any questions you like. I'll answer them if I can, but sometimes I'm not allowed to tell you, because I have to follow the rules.
Then I answer their questions, and we do some warm up chitchat and drawings for a few minutes, before starting formal testing.
