Draw a large a and a large an on separate pieces of paper. It is best if these words are written inside amusing animal shapes. Divide the class into two teams. The first child from each team puts their hands on their heads. Show the children a vocabulary flashcard. They both touch (or slam) the a or an . The one to touch the correct paper first gets a point for her team, provided that she says, It s a or It s an correctly. If she makes a mistake, the other child is offered a chance to make the correct sentence. After the class gets the idea, one of the children can hold up the cards instead of the teacher.
