I have... Who Has with capital letters set up for center practice.
Typically with this game it is set up with a begining and an end. I have it set up to play as a center game without the teacher for independent practice.
I lay all of the cards out face up so that a pair of students can play. One student picks a card and read it. The other student then needs to look for the letter the first student asked for. Cards get put back on the table face up so that the game could essentially go on for as long as you wish. This way students are able to be independent in their practice and can have the repetition that is so important for our young students.
Can also be used as an assessment of letters out of typical order.
