I Have... Who has? is one of my kids favorite games. It helps develop listening skill because student must listen for the question that they might have the answer. I do not have my cards numbered because it makes the students listen closer to hear their questions. I also have the students to work with a partner to practice reading their cards for fluency before we begin the game.
I print my cards out on card stock. This saves me time and work.
I used customary and meter measurement.
