21. GAMETips To be successful, follow some of these tips. Say the number quickly and clearly. If the birthday student does not understand, repeat the number slowly. It’s better to say the number slowly and correctly than faster and incorrectly. If the math is not correct, the birthday student probably misunderstood a number incorrectly. The birthday student should ask the other students on the team to repeat. If it is not your turn, be quiet! It can be difficult to hear when too many people are talking.
