I prepared this set for my students. I believe it will make learning Polish even more enjoyable :)
What you need is 2 sets of alphabet. One becomes a control sheet (if needed) and the other one gets cut into pieces (seperate letters) that can be used to build the alphabet. You can also play a simple matching game, introduce "Gdzie jest..." question and more (I'm sure you've got your own ideas and goals). My set includes words on the back and is laminated.
