Let me tell you my name and why I am here today. My name is and I work with. We are trying to understand how children learn mathematics. You were picked by chance like in a raffle or lottery. We would like your help in this. But you do not have to take part if you do not want to. We are going to play a mathematics game. I am going to ask you simple mathematics questions. Using this stopwatch, I will see how long it takes you to solve a problem. This is NOT a test and it will not affect your grade at school. I will NOT write down your name so no one will know these are your answers. Once again, you do not have to participate if you do not wish to. Once we begin, if you would rather not answer a question, that's all right. Do you have any questions? Are you ready to get started?
