I used this activity during field experience with a student working on the /wh/ digraph in phonics. It worked really well, and the student enjoyed the life-size cards aspect of it. This activity hasn’t been used in a large group before, but I believe it should work well with 2-4 players.
This PDF file includes 18 different matching cards as well as a blank template for you to add what you like to it. When printing these documents, print on both sides (flip page on short edge). Also, it is better to use thick paper so that the paper isn’t transparent.
